The video then goes into action-packed scenes of Alex fighting off and running from his enemies. As Number Four's love interest, Sarah, Dianna is caught in the mix, finding herself as much of a target as the extraterrestrial beings.
As you know by now, the movie is a big scree adaptation of James Frey and Jobie Hughes' young adult novel of the same name.
After being displaced from their just-destroyed planet, nine aliens, including Number Four, seek safety on planet Earth, but their enemies are right on their trail.
Check out the new teaser below. You'll even get to see a wide shot of Alex and Dianna, who are rumored to be dating, sharing a sweet kiss -- but don't blink or you might miss it. I Am Number Four will be released on February 18. Are you excited for the movie?
