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 ''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.'''
