Gabrielle Union, Ed Helms and Elizabeth Banks are joining Eddie Murphy on 20th Century Fox's sci-fi comedy "Starship Dave" says The Hollywood Reporter.

Based on a script by Rob Greenberg and Bill Corbett, "Starship" centers on a spaceship that takes the form of a human (Murphy). It's operated by 100 human-looking, quarter-inch-tall aliens seeking a way to save their planet.

Complications ensue when their captain (also played by Murphy) falls in love with an Earth woman named Gina (Banks), a hip, downtown artist who always picks losers to date.

Union plays the chief cultural officer of the miniature crew, Helms is the uptight second-in-command. Directed by Brian Robbins ("Norbit"), shooting is set to begin in the next few weeks.
