This test footage for Who Framed Roger Rabbit has been doing the rounds this weekend, but you may have missed it. It's interesting because Jessica and Roger have rather different looks, particularly Roger; and because Paul Reubens has given Roger his Pee Wee Herman voice. It dates back to early 80s and predates both Robert Zemeckis and animation director Richard Williams' involvement.
This is a slightly more complete video to the one most folk are running.
Not a bad first run at the characters at all. Things did develop for the better, and significantly so, but the foundations were strong at least.
And, while we're here, let's have some Roger Rabbit 2 test footage from the late 90s.
