examples

Some examples of using 2D animation with live action footage include who framed roger rabbit (1988), and space jam(1996). 2 very successful, very popular movies. I think the secret to making the two things look like they interact if probably the use of shadow and reflection, making it look like the animated thing is actually there. Also the acting of the characters is obviously very important, having the correct eye line. Another factor would probably be lighting. If a scene is set in a low light situation and the live action stuff is really dull, then you don't want your animated characters looking like they are in full sunlight.
