Alec Baldwin, Gemma Arterton And Sharlto Copley Joining 'Men In Black 3'?

Gemma ArtertonCasting is coming together for "Men In Black 3," and the names of those newly announced should get you plenty pumped for the upcoming threequel. The film will take place in both the present day and in 1969, and follow the MIB employees -- Will Smith's Agent J and Tommy Lee Jones's Agent K -- that we have come to know and love, as well as some newcomers.

According to Pajiba, Alec Baldwin is in negotiations to come aboard as the '69 Men In Black boss, while erstwhile Bond girl Gemma Arterton would play a secretary during that same period. "District 9" and "A-Team" star Sharlto Copley, meanwhile, is in negotiations to play what Pajiba describes as a "fast-talking Yoda type alien."

The trio would join the previously cast Jemaine Clement, Josh Brolin and Emma Thompson. Brolin is playing a young Agent K from 1969, while Thompson will be the head of MIB in the modern day. Then there's Sacha Baron Cohen, who will be voicing an alien named Boris.

Clement is playing a villain named Yaz who travels back in time to 1969 in order to kill Agent K, which will destroy the Earth in the present day. "Dancing With The Stars" champion Nicole Sherzinger has been offered the role of his girlfriend.

Filming is set to start in New York City next month, and is expected to run through February. If the previous films are any judge, expect news of plenty more cameo appearances over the next few months.
