Quite a few shots of the WP (modified for film) interface in the film. Defo wasn't a Lumia though...
Meh, it was a fun movie. It feels small in scale (I think there's only like 10 speaking roles in the whole movie), inexpensive and has a short runtime for movies these days, but it was fun and kid-friendly. And hearing my son lean over and say "They have a lot of Windows Phones in this movie!" made my day.
