Jonah Hill asked producers not to hire Christopher Mintz-Plasse in Superbad

Jonah Hill asked for one of his Superbad co-stars to not be cast in the cult classic.

Look, few films define 2007 quite like Superbad - the teen comedy is a masterpiece - and while you’re probably aware that Seth Rogen and Evan Goldberg are behind what has to be one of the funniest movie scripts of all time, you probably don't realise that star of the show Jonah Hill couldn't stand Christopher Mintz-Plasse.

Yep, turns out that Hill found the iconic McLovin' actor 'annoying' from the outset.

Check out the trailer for the hit film here:

For those not familiar with the film, and seriously where have you been, it centres around: "Two co-dependent high school seniors are forced to deal with separation anxiety after their plan to stage a booze-soaked party goes awry."

Those two seniors just so happen to be Hill and Mintz-Plasse, who didn't quite hit it off on first meeting in real life.

As producer Judd Apatow told Vanity Fair: "Jonah said, ‘I don't like that guy. I don't want him doing it.’ And I said, ‘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'."

Creator of the film Rogen added: "Jonah immediately hated him. He was like, ‘That was f***ing with my rhythm. I couldn't perform with that guy."

Not exactly best friends forever, however, Hill still praises his co-star's performance and the pair seemed to work things out just fine: "Chris was really, really amazing off the bat. And I think he was really annoying to me at that time."

However, theirs wasn't the only tension on set, as it turns out that the 2007 film was rife with awkward, annoying moments.

For instance, Mintz-Plasse, who was 17 at the time of filming, described the 'very, very surreal' moment his mum had to watch him film his infamous McLovin sex scene.

Obviously, she was on set for legal reasons, not by choice, as the actor explained on The Rich Eisen Show: "[My mother] did not have to be there for everything, but she 100 percent had to be there for the sex scene, absolutely."

When asked if it was uncomfortable, McLovin of course answered: "Yeah, it’s definitely uncomfortable when you’re – at the time, I was actually a virgin, so I had no idea what I was doing.

“I was very nervous, very scared, and then I look over to Video Village [the nickname given to the area around the monitor on set] and my mum is eating a handful of popcorn talking to the producers.

"She was having the time of her life!"

Yep, sounds like quite the filming process.
