Gabrielle Union, Elizabeth Banks and Ed Helms have signed on to ride with Eddie Murphy on the 20th Century Fox comedy “Starship Dave.” The script centers on a spaceship that takes the form of a human, played by Oscar nominee Murphy. It’s manned by 100 human-looking, quarter-inch-tall aliens in search of a way to save their planet. But trouble arises when their captain, also played by Murphy, falls in love with an Earth woman who always picks losers to date. Union will play the chief cultural officer of the miniature crew. I wonder who then will play Eddie’s love interest?
