Barry Sonnenfeld ''can't wait'' to do 'Men In Black 4'.

The director of the film franchise has dropped his strongest hint yet that there will be a fourth movie in the series, which he believes has been ''refreshed'' after Josh Brolin joined Will Smith and Tommy Lee Jones in 'Men In Black 3'.

Speaking at the UK premiere of 'Men in Black 3' in London's Leicester Square last night (16.05.12), he told BANG Showbiz: ''Josh not only didn't ruin the franchise but it's literally renewed now, its refreshed and I can't wait to see what happens in 'Men In Black 4'.

''We'll see how this movie goes but anything is possible and it would be great to do it.''

Despite the 10-year break between 'Men in Black 2' and the current movie in the franchise, Barry felt he hadn't seen Will and Tommy for one weekend rather than a decade, and he admitted it was ''really easy'' to go back to the series.

He added: ''Stepping back into 'Men In Black' with Will Smith and Tommy Lee Jones and now Josh Brolin was really easy. The first time Will, Tommy and I met it was like we hadn't seen each other for the weekend not 10 years. Then they put on the suit and they start acting - it was fantastic.''

'Men In Black 3' sees Agent J (Will) go back in time to the 1960s to stop an alien from assassinating Young Agent K (Josh) and changing the future for Agent K (Tommy).

Joining Barry on the blue carpet at the premiere were stars of the movie including Will, Josh, Nicole Scherzinger, Emma Thompson, Alice Eve, and rapper Jay-Z was a surprise late arrival to the event.
