Men In Black director Barry Sonnenfeld has confirmed Will Smith and Tommy Lee Jones's involvement in the new sequel.

Sonnenfeld reportedly told Showbiz 411 that, despite rumours of Smith's departure, the actor has signed on to return alongside Jones.

The filmmaker added that the movie will also be made in 3D and could be the big blockbuster release for May 2011's Memorial Day weekend.

The first two Men In Black movies, which starred Smith and Jones as covert agents monitoring aliens on Earth, grossed a combined $1bn at the worldwide box office.
