Screenwriters Jay Reiss and Ian Hefler got plenty of love at Saturday night’s premiere of ensemble comedy “The Oranges” at the Toronto Film Festival.“The script. The script. The script. The script. The script. The script,” was Oliver Platt’s response to a question as to why the on-screen chemistry of “The Oranges” works during a Q and A at the Winter Garden theater. Platt had pointed out the scribes in the audience before delivering his response. Julian Farino was similarly fullsome in his praise at the premiere. “Everyone tells me how much they love the script, which ratchets up the pressure,” said Farino in introducing the pic. Cast members Hugh Laurie, Allison Janney, Alia Shawkat and Leighton Meester attended the premiere.
