Men in Black III will feature “retro” aliens from the past, according to the film’s lead make-up artist.

Will Smith and Tommy Lee Jones are returning for the third film of the sci-fi franchise, which will see Agent J (Smith) travel back in time to meet a younger version of Jones’s Agent K, to be played by Josh Brolin.

Special effects make-up artist Rick Baker revealed that the aliens featured in the film will have a “B-movie” style of the 1950s and 1960s as opposed to modern day versions.

“The thing that’s cool is there is a time travel element [to the story],” he told Coming Soon.

“Where I had fun is that we go back to the Men in Black headquarters of the ’60s. The first thing I said is that we should have retro aliens, not aliens of 2012. More based on B-movies of the ’50s and ’60s. So, a lot of the aliens are based on that. Space suits with fishbowl helmets and ray guns.”

Jemaine Clement, Emma Thompson, Nicole Scherzinger, Alice Eve and Michael Stuhlbarg will also appear in science fiction comedy.

Men in Black III will also be released in IMAX 3D theatres when it is released on May 25, 2012.
