Regal policy is that in order to see an R rated movie a person has to be at least 17 yrs old with an ID or with someone 21 yrs or older with ID. They don't have to have the same last name the adult just has to stay in the movie with them.
I don't know. I am older so I could not know
They will make sure you have an adult with you.
Oh so required for check last name or what
I don't think anyone checks last names.
