12)Don't know
13)$12
14)A science experiment
15)Copernicus and Einstein
16)Horse broke down, bear ate his boots, forgot his hat
17)Einstein (He does appear in all 3)
18)Pinball machine parts
19)$5 for the whiskey and $75 for the horse

And no extra credit for me. Wow, I thought I knew all about these movies. My head hurts now...
