Chris Miller admits a 'Men In Black' and 'Jump Street' crossover movie is an ''interesting concept''.

The 39-year-old director - who helped to create the 'Jump Street' franchise - has responded to speculation regarding a film that brings the two brands together - an idea that was first mooted in leaked Sony emails.

He admits: ''It's a really interesting concept.''

However, Miller was keen to stress that the much-discussed idea remains a long way from being realised.

The director told ComingSoon.net: ''It's very, very early on in this crazy fever pitch, but it definitely makes you think.

''Talking about it, developing it with Jonah Hill and Channing Tatum and Rodney (Rothman, co-writer) and the studio, we can't just do the 'Hey, it's the same thing again'-schtick because we did that already.''

Meanwhile, Miller also addressed the issue of movie sequels, admitting that some plot-lines lend themselves to follow-up films, while others don't.

Speaking specifically about the 'Jump Street' franchise, he explained: ''We knew we thought there's a lot to say about sequels and they're really hard to execute well, especially comedies.

''Luckily, Jump Street is a police procedural so it has a built-in sequelness to it already. That definitely helped. That's why you can do four million Bond movies and no one's like, 'Oh, it's the same movie.'''
