Research - Catch Me if You Can Title Sequence

When looking at this sequence i feel that it has a home made feeling to it for a number of reasons. The first being the fact that it has a Saul Bass style to the figures and sets. The second reason that I think it looks handmade is because it feels and looks as if the figures have been drawn and scaned in and layered then animated while layered. Finally the last element that makes it look Handmade is the animation of the cars, this is because the animation is not smooth it moves in a much more squareed/blocked style
