Building from elements of Valve's praised and popular video game series Portal, Dan Trachtenberg made this short film about a Ripley-esque heroine being held against her will. It's a well done clip -- the special-effects in particular are impressive-- and it's only five minutes long, so check it out for yourself above. On YouTube, it's already clocked over 1 million views in 24 hours.

And if you haven't played Portal, it's available now.
