How exactly do you know when you're really in love? In the new trailer for How Do You Know, Reese Witherspoon asks herself exactly that. As professional softball player Lisa, Witherspoon questions her relationship with Manny (Owen Wilson), a major league baseball player who's not sure what he wants either. To make her situation even more complicated, she crosses paths with George (Paul Rudd), a charming down-on-his luck corporate exec whose life seems to be circling the drain.
The trailer for the romantic comedy is more somber than slapstick, but that's not necessarily a bad thing. Witherspoon gets a break from her typically type A characters to play someone who doesn't have it all together — though Rudd and Wilson are predictable as the lovable everyman and clueless-but-funny airhead, respectively. It could go either way on the cliched movie meter, but the cast is just too good to resist. It opens on Dec. 17, but get a peek after the jump.
