An R rated movie "under 17 requires accompanying parent or adult guardian" . They shouldn't let either one of you inside.
I am not sure
I'm surprised you could go see it. Usually R rated is 17 or 18 and up, but if they don't ask for ID, then yeah you both should be able to get in. It depends on who's working the ticket booth that day man, good luck
A 5 year old might be a but young for Deadpool. He wouldnt get most of the movie, and there is a lot of violence that a 5 year old shouldn't see and language that a 5 year old shouldn't use.
