There are lots of primarily live-action movies these days that incorporate some degree of computer animation, which may or may not be noticeable, and may or may not be of particular importance to the plot or overall look of the movie. I'm not even going to try to list every such movie, but I do at least want to list movies where CGI elements (including characters, backgrounds, etc.) are quite obvious and important.

Note: right now I'm listing (almost) any movies I've seen or want to see that are on Wikipedia's lists (as long as they're mostly live-action). When I have more time/inclination, I want to go through the list and mention specific CGI elements in each film. I may also remove some films from the list if they don't meet my own standards of "important" elements, as well as potentially adding films that aren't on Wikipedia's list. Edit: Since I first started this page, the Wikipedia lists I referenced have been deleted, much to my dismay.
