Men in Black 3?

REPORT: The men in black are massing.

Sony Pictures is moving forward on "MIB 3," the third movie in its sci-comedy franchise.

"Tropic Thunder" writer Etan Cohen is penning the script, and Barry Sonnenfeld, who directed the first two films, is said to be attached to the new installment, though there is no formal deal or offer as yet.

The studio is eyeing a 2010 start date for the production.

The X factor remains Will Smith. The A-lister, who starred with Tommy Lee Jones in the first two "Men in Black" films, has not committed to the project, though in recent days the buzz in development circles has been that he is interested in returning. Smith does not have a pending movie project lined up.

Jones' involvement is uncertain.
