LAS VEGAS -- Warner Bros. Motion Picture Group president Jeff Robinov -- who will inherit greenlight authority after studio president Alan Horn retires Friday -- made his first visit to the annual convention of theater owners on Thursday, promising that the studio will continue to make a diverse slate of films.

Keeping with tradition, Warners was the last studio of the convention -- now called CinemaCon -- to present footage from its upcoming films, including the world premiere of the first trailer for Todd Phillips' The Hangover 2 and several minutes of footage from Harry Potter and the Deathly Hallows: Part 2.

Warners also showed extended footage from Ryan Reynolds superhero pic Green Lantern, with Reynolds taking the stage, as well as recapping the studio's No. 1 standing at the worldwide box office last year.

Robinov is one of three executives who will ascend to the office of presidency next week. The other two are home entertainment executive Kevin Tsujihra and television veteran Bruce Rosenblum.

Robinov profusely thanked exhibitors for their "unparalleled support." The sentiment was repeated by Warners president of domestic distribution Dan Fellman -- who led the show -- and international president of distribution Veronika Kwan-Rubinek.

But the timing of Warner presentation was unfortunate for the studio. Earlier in the day, theater owners reacted with fury when finding out that Warners, Fox, Sony and Universal are planning to shrink the theatrical window and offer a premium VOD service 60 days after a film is released in theaters.

Exhibitors were still eager to see Warners' strong slate, however, and responded with the customary applause after the various executives spoke. Neither Robinov nor Fellman mentioned the dust-up.

Phillips, who took the stage to introduce the trailer for Hangover 2, addressed the issue directly, however. He told theater owners he sides with them on the issue of premium VOD. Theater owners clapped loudly, while hoots and hollers could be heard.
