Take a look at 2010's best 3-D family movies, present by LIonsgate's 'Alpha and Omega.'

Thanks in part to the overwhelming success of James Cameron's 'Avatar,' 2010 is the year 3-D movies became so ubiquitous that theater chains invested in child-sized glasses, so even the youngest moviegoers could enjoy the technology. It's a good thing, too, because the majority of 3-D movies are family-friendly films. While some are waste of the designation ('Clash of the Titans' comes to mind), others make the momentary inconvenience and surplus fee worth while ('How to Train Your Dragon').

This fall kicks off with even more 3-D releases, like 'Alpha and Omega' (Sept. 17), a kid and tween-friendly adventure following two wolves from different sides of the pack -- Alpha female Kate (voiced by Hayden Panettiere) and an "Omega" male Humphrey (Justin Long). The two young wolves end up separated from their friends (who include wolves voiced by Danny Glover and Dennis Hopper); and as with all great love stories, they get to know and like each other on their action-packed journey back to their pack.

But before families had back to the theaters for fall's big 3-D releases, let's take a look back at the year's five best 3-D family titles.
