'The Interview': Why It Could Only Ever Have Been James Franco And Seth Rogen

'The Interview' has already become arguably the most controversial comedy of the moment, with its less than sensitive approach to the crisis in North Korea. Nonetheless, it's another tremendously funny venture from a comedy duo we just can't get enough of.

James Franco and Seth Rogen appear to be simply inseparable at the moment; having been best buddies since meeting on the set of late nineties show 'Freaks and Geeks', the pair have collaborated on numerous projects such as 2008's Golden Globe nominated 'Pineapple Express', Evan Goldberg's memorable 'This Is the End' (in which they play themselves) and Franco's own film adaptation of William Faulkner's 'The Sound and the Fury' (yeah, we couldn't imagine them doing 'serious' either).

'Franco's the best, we get along really well, we're funny together', Rogen admits of his friendship with the Oscar winning star. And that joint humour that they share certainly hasn't been missed by their co-stars on 'The Interview', as Diana Bang insists 'seeing Seth and James work is a masterclass in improv'.

Individually, they are perfect for their respective roles too, with director Evan Goldberg explaining that Franco was the best guy to play Skylark 'because Franco's crazy and so is his character'. Even co-star Lizzy Caplan - who plays the seductive Agent Lacey - admits: 'I feel like Franco's been gearing up to unleash this character on the world.'

The fun doesn't stop at 'The Interview' either; you'll be seeing a lot more from Franco and Rogen in the coming months as they currently film for Goldberg's forthcoming animated comedy entitled 'Sausage Party', as well as James Franco's upcoming flick 'Zeroville'.

'The Interview' is set to hit movie theaters on February 6th 2015.
