But it turns out there's one person who didn't grow up watching Rupert in Harry Potter, and that person is...Rupert himself.
In an interview with Variety published on Thursday, the 32-year-old admitted he's "probably" only ever seen the first three movies.
Don't worry too much, though — he went on to say he expects he'll have to catch up on the rest of the movies in the future now he's a father.
Rupert's partner of 10 years, Angus, Thongs and Perfect Snogging actor Georgia Groome, gave birth to their daughter, Wednesday, in May last year.
"Now that I have a daughter, I will probably have to watch them with her," he told Variety.
