Now that we have a deal between Time Warner Cable and CBS, we can turn our Hollywood focus back on the movie industry.

Steve Julian: Business analyst Mark Lacter, would you agree it's been an up and down summer at the box office?

Mark Lacter: It's been a flaky summer for Hollywood, Steve.  On the plus side, ticket revenue was up more than 10 percent, and attendance increased around six-and-a-half percent compared with last year (this covers the first week of May through Labor Day weekend).  The problem is that the studios and their investors spent huge amounts of money to make a lot of these movies, and they had to compete in a very crowded market - 23 big-budget films came out this summer, which is way higher than normal, and some of them never had a chance.

Julian: Some examples?

Lacter: Probably the biggest clunker was "The Lone Ranger," which could end up losing close to $200 million for Disney.  Another big disappointment was "White House Down," which was distributed by Sony and brought in only $140 million, which for a big-budget action film is really bad.  Even a film like "Pacific Rim," which did well at the box office, might still end up in the red because the production and marketing costs were so high.

Julian: And summer, of course, is the time when studios want to bring out these monster releases -

Lacter: - right, what they call "tent poles" - and in that category, the biggest winner was Disney's "Iron Man," which took in $1.2 billion.  Also having a great summer was "Monsters University" from Pixar, with $700 million.  You also had "Despicable Me 2" and "Fast and Furious 6," which might not be our cup of tea (speak for yourself, it takes me back to my police car days!), but did very well for Universal.  Eight of the top 12 films this summer were sequels - and yet, sequels were no guarantee of success (a number of them really struggled).  And, some non-blockbuster films found considerable success: "Now You See Me" from Lionsgate only cost $75 million to make.

Julian: So, in some ways, Hollywood was its usual unpredictable self.

Lacter: That's right - and don't expect any big changes in strategy when it comes to big-budget films.  The prospect of having huge success with one of these blockbusters is just too great, but perhaps more important is the fact that many of these films are financed by multiple groups of investors, and so the risk is spread around.  It's not like the old days when a studio bankrolled the whole thing.

Julian: Though, sounds like it's bad news for the city of Los Angeles: the "Man of Steel" sequel is going to be shot in Michigan?

Lacter: Mayor Garcetti has actually declared a state of emergency because the city keeps losing business to other states that offer big tax incentives to films - what's known as runaway production.  The truth is that business has been lost over the years, but L.A. is hardly in any danger of losing its spot as the center of entertainment.  And, you can see that with the L.A. County Board of Supervisors signing off on Disney's plan for a TV and movie production facility near Santa Clarita that will add more than a half-million square feet of studio space.

Julian: And, Universal's expanding, too.

Lacter: Earlier this year, Universal was given the approval to build more production facilities, and Paramount is planning an expansion, as well.  Now, these are all very ambitious projects - not the sort of investments that would be made if these studios were looking elsewhere to make movies and TV shows.  And, of course, they mean jobs - actually, employment levels in the entertainment industry have remained fairly steady going back the last decade.

Julian: Are there states that are pulling back their incentives?

Lacter: Yes, the state of North Carolina, which has been especially aggressive in using tax incentives to draw in movies and television going back to the 80s, is phasing out the giveaways because legislators have decided that the economic benefits aren't worth the tax revenues being lost.  And, other states with tax incentive programs are pulling back as well - they're finding that the payback is very difficult to measure.

Police say TSA agent Gerardo Hernandez was shot and killed last Friday at the base of the escalators of LAX Terminal 3, and not at the checkpoint gates.  Paul Ciancia is accused of killing Hernandez and wounding several others.  Ciancia remains hospitalized in critical condition.

Steve Julian: Business analyst Mark Lacter, how did the airlines respond to shooting and its aftermath?

Mark Lacter: Generally pretty well, Steve, considering that the airport was effectively closed for several hours on Friday, and most of Terminal 3 was out of commission until Saturday afternoon.  You know, there's always this precarious balance in operating airlines and airports, even in the best of circumstances.  Just so many flights coming in and going out, and so many thousands people using the facility at any given time - and it really doesn't take much to upset the balance.  So, when you have something horrific take place and you see all those travelers stranded outside the terminals, the ripple effects are enormous - not just at LAX but all over the country.

Julian: More than a thousand flights were either canceled or delayed on Friday.

Lacter: And, there was a further complication because the airlines flying out of Terminal 3 are not the legacy carriers like United, American, and Delta that have all kinds of resources, but smaller operations with less flexibility.  It's not like there's an empty aircraft just sitting in a hangar waiting to take passengers wherever they want to go.  Actually, the airlines have gotten better at arranging re-bookings when there's a snowstorm or some other emergency that gives them advance warning.  But obviously, there was no advance warning last Friday, so the carriers needed to improvise in handling passengers whose flights were cancelled.

Julian: What did they do?

Lacter: One step was waiving the fees normally charged to re-book flights (and that's gotten to be a pretty penny).  Another was waiving the difference in the price of the original ticket and the re-booked ticket.  But, the policies varied according to the airline, and we heard about travelers not receiving hotel or food vouchers, or having to buy a brand new ticket on another airline if they wanted to avoid the wait - and that can be expensive.  Which raises another issue: planes tend to be completely full these days because airlines have been cutting back on the number of flights.  And that can be a problem if you're taking a route that doesn't have too many flights in the first place.  So, it gets really complicated.

Julian: Why do you think we haven't we heard more horror stories from passengers?

Lacter: Well, look at the cities that the airlines in Terminal 3 fly to - New York, San Francisco, Seattle, Dallas.  They're all served by several other carriers.  L.A. to New York, in particular, is one of the busiest routes in the world, which means that it's also one of the most competitive.  So, even if your flight was cancelled, there's a good chance you'd be able to find space by Saturday (which is normally a slower day for air travel).  This is a big reason, in general, why people like LAX.

Julian: Why don't other local airports handle more of the load?

Lacter: You might remember a few years ago local officials were promoting something called "regionalization" - the idea was that as LAX maxed out on the number of passengers it was allowed to handle each year, then other airports would make up the difference - places like Ontario, Bob Hope in Burbank, and John Wayne in Orange County.

Julian: Right, and they talked about easing traffic congestion by spreading around the flights.

Lacter: Well, regionalization never happened because, first of all, passenger levels at L.A. International didn't come close to maxing out.  But, more importantly, because the airlines decided that using LAX was more efficient for everything from handling baggage to arranging international connections.  So, through the first nine months of the year, passenger traffic at LAX is up 4.2 percent from a year earlier, while at Ontario traffic was down 9.3 percent.  And, we've seen that John Wayne, Bob Hope, and Long Beach are all struggling.  Of course, the challenge at a busy place like LAX is making it as safe as possible, and that will no doubt become a priority in the weeks ahead.

Two grass species that had been relatively rare in the plots, Spartina patens and Distichlis spicata, began to respond vigorously to the excess nitrogen. Eventually the grasses became much more abundant. Nitrogen ultimately changed the composition of the ecosystem as well as its capacity to store carbon.
