This is a screenshot of the food. What is it?  It appears in the original movie in at 49:28. 
Those are canapes: little bites of something tasty. Being served on a silver tray implies they are expensive and were made with care and time, letting us know that this setting (I know nothing about the movie and haven't followed your link) is rich and luxurious. The black blobby stuff is probably supposed to be caviar, the white piped stuff probably some sort of creamy filling. The red could be fruit, or a red caviar / salmon roe kind of thing. (It would be odd to have sweet and not-sweet on a tray together.) Other visible garnishes include sprigs of parsley and "cheeks" of olives. The beige cylinders are probably puff pastry or bread and the green ones probably carved cucumber. A comment on the other answer points out you could use a fluted cookie cutter to cut both bread and cucumbers, and that seems really likely in a catering context. [In movie-set reality these things might be play dough or mashed potatoes or anything else a prop person feels like using.] Would you need more detail than that? Why?
