12splitfacething.jpg In the 2011 remake of The Thing, Eric Christian Olsen and Trond Espen Seim play a two-faced alien monster. Being an alien twin in utero must be hard because of all the vicious sibling attacks. 2lawandorderguy.jpg Law & Order star Vincent D'Onofrio gets outed as an alien in Men in Black. Which gives us a great idea for a show set around a wacky courtroom in outer space. 4slither.jpg In Slither, Brenda James becomes pregnant with thousands of alien slugs. Which is why alien birth control pills are just salt tablets. 5drwho.jpg In the Australian Doctor Who spinoff, K-9, Cathey Robinsen plays a member of an all-female race of alien librarians. We're guessing they all come from the planet "Shhhhhh!" 6ryanborg.jpg Jeri Ryan played a formed Borg drone on Star Trek: Voyager. We suspect her curves were too distracting for the hive mind. 7chipochungdrwho.jpg Chipo Chung played an alien named Chantho in the Doctor Who episode, "Utopia." If the goal was to make it look like a giant insect crawled onto her face, they succeeded. 11sonyaandromeda.jpg Sonya Salomaa plays the force lance-savvy Uxulta on Andromeda. One problem with being a blue alien is that others can never tell if you are amphibious or just drowning. 12chatelain.jpg Christine Chatelain was transformed for the Andromeda episode, "The Spider's Strategem." She definitely left us wanting to know more, such as what vacuuming attachments are compatible with her mouth. 7claudiakarvan-1.jpg Popular Australian actress Claudia Karvan played Natira on Farscape. She uses her head appendages to claw out her enemies' eyes and, we assume, for relaxing scalp massages. 8earthfinalconflictkari-1-1.jpg Kari Matchett played Siobhan Beckett and Rho'ha in Earth: Final Conflict. We imagine that people with big ears and big brains get massive headaches from loud noises. 9wraith-1.jpg Jewel Staite transformed her fair form to play a wraith in Stargate Atlantis. Interestingly, both pictures look the same after six drinks at the bar.
