But the lead actor admits he's not stayed in contact with his screen friends since they filmed the first few movies in the early 2000s.
He tells EW.com, "It was kind of surreal being back with everybody (at the script read through). Not everyone was in the third movie so there were people I haven't seen since the second film. A lot of us have not really kept in touch.
"Some of us are not really friends. But it doesn't mean we're not friendly when we see each other. I'll probably remember how irritating some of them are in the first week and let you know."
