Jonah Hill 'immediately hated' Superbad co-star at auditions

It turns out that the cast Superbad weren't as good friends in real life as they seemed to be on screen, with Jonah Hill admitting he 'immediately hated' one of his co-stars upon meeting.

It will be very hard to come across someone who hasn't seen the 2007 cult classic, with the movie still continuing to cement itself as one of the most iconic comedies to ever exist 16 years on from its release.

Following the story of students desperate to end their high school careers with a bang, the film saw Jonah Hill (Seth) and Michael Cera (Evan) attempt to get some alcohol and make it to a party thrown by one of their classmates, played by Emma Stone.

Though Cera and Hill might have already been familiar to fans, it was Christopher Mintz-Plasse who stole the show as McLovin - no last name.

His performance as the over-confident but dorky high schooler remains iconic to this day, and while executive producer Judd Apatow knew the role belonged to him, Hill wasn't so sure.

Mintz-Plasse was cast after open auditions for the role of McLovin, which he tried out for along with a number of his friends from drama class. He was the only one to get a callback, and he went on to read for the role alongside Hill and Cera.

Recalling the audition process, Hill admitted to Vanity Fair that Mintz-Plasse was 'really, really amazing off the bat', but added: "And I think he was really annoying to me at that time."

Apatow remembered Mintz-Plasse being 'very caustic', adding that he 'attacked Jonah and did improvs insulting Jonah'.

Seth Rogen, who played Officer Michaels, added: "Jonah immediately hated him. He was like, “That was f**king with my rhythm. I couldn’t perform with that guy.'”

Apatow claimed Hill had told him he didn't 'like' Mintz-Plasse, saying, "I don't want him doing it," but the executive producer replied: "That’s exactly why we’re hiring him. It couldn’t be more perfect.

"The fact that it bothers you is exactly what we want."

The actor, who was just 17-years-old at the time, said he was 'super stoked' to be there and admitted to having everyone sign his script because he didn't think he was going to get the part.

Obviously, Mintz-Plasse did ended up being cast, and though Hill might not have been on board at first, I think we can all agree it was the right choice... because seriously, who else could have played McLovin?!
