Fantastic Four is probably going to suck, admit Fantastic Four cast

'Rarely are films of this size critically well-received'

The cast of Fantastic Four know what it's like to be a critical darling – Miles Teller did Whiplash, Kate Mara did House of Cards, Michael B. Jordan was in The Wire and Jamie Bell featured in Nymphomaniac – so they are under no Vin Diesel-esque illusion that their CGI-laden superhero blockbuster is going to be well-received.

They've been so busy doing promo for the Marvel film that they haven't gotten around to actually watching it yet, but they can pretty much guess what’s coming by this point.

"I'm going to try to see it opening night with a real audience," Mara told Newsbeat.

We haven't seen the film either. Rarely are films of this size critically well-received," Teller added.

"This is not a movie we're going to go on (review website) Rotten Tomatoes and it's going to be at 80 or 90%."

Critics have not been given the chance to see the movie ahead of its release, usually a sign that the most Rotten of Tomatoes awaits.

This probably won't harm it's box office chances though, and the movie is set to easily recoup its $122 million budget.

Fantastic Four hits cinemas on August 6 in the UK and August 7 in the US.
