films using motion capture
This is a grossly incomplete list. You can find a lot more films that used motion capture on Wikipedia. Many of those mentioned I haven't seen, and many of the ones I have I wasn't aware of mo-cap being used, or I'm not sure how much it was mo-cap and how much it was normal CGI.

all CGI:
The Polar Express (2004)
Final Fantasy VII: Advent Children (2005)
Monster House (2006)
Beowulf (2007)
A Christmas Carol (2009)
The Adventures of Tintin (2011)
Mars Needs Moms (2011)

mostly live-action:
