Sunday in the Afternoon

This Sunday, I went with my family to the cinema. We watched the movie "Carta al niño Dios", it's good. We ate popcorn, sandwiches and soda.  It's a Colombian movie.  The main characters are Ruben, his son Rubencito, ex-wife Mireya and her boyfriend Renzo, and (Ruben's/Renzo's?)?) best friend Raul, the priest.  It's a comedy. We liked this movie. 

Please, correct me.  Thanks.

There was one line where you mention Ruben, his son, his ex-wife, ect. but i wasn't sure who they were. Were they actors in the show? Other than that, I fixed some minor mistakes, but overall, good job.
