Finding more talents to get onboard "Starship Dave", the 20th Century Fox has submitted Elizabeth Banks, Gabrielle Union, and Ed Helms into the flick's cast, which has already had Eddie Murphy in to topline.

A fish-out-of-water comedy, the project revolves around a spaceship that takes the form of a human operated by one hundred human-looking tiny aliens who seek a way to save their planet. Murphy will play both the ship and its captain while Banks is billed as an Earth woman whom he falls for.

As for Union, the "Daddy's Little Girls" star is poised to be the chief cultural officer of the miniature crew with Helms portraying the crew's uptight second-in-command. Filming is due to begin in the next few weeks under the direction of Brian Robbins, who will helm from script by Bill Corbett and Rob Greenberg.
