Love that movie and own the DVD.I recently bought the Revell 1941 P-40 warhawk model off of Ebay for about $10.
Best scenes:
The opening with Wild Bill smashing coke bottle and gargling it.
The B-17 cockpit with woman in red dress
and the two guys on watch on ferris wheel when after the older guy tells the nerd to shut up,out pops the dummy dressed as the old guy.....bahahaha,then he drops his cigar.
