Ya know another Movie truck that could be built from an existing kit would be the "Porkchop Express" from Big Trouble in Little China. It was kind of a corny movie made in the late 80's with Kurt Russell and Kim Cattrall in it.. it had this sweet Freightshaker FLC120 with a 60" standup and an extra set of airhorns on top of the bunk even! I was thinking about snagging another Italeri FLC and building one. Best scene in the movie was when he fires that truck up and revs it up and Kim Cattrall says what was that? and Kurt Russell replies "A 6.9 on the Richter Scale baby!" lol i loved it! Sooo thats just an idea.. build myself a Porkchop Express in fact heres a pic.
I have had the Porkchop Express on my to do list for several years. Big Trouble in Little China is a favorite of mine, it's kind of cheesy but it knows it is which makes it all right.
Just remember what ol' Jack Burton does when the earth quakes, and the poison arrows fall from the sky, and the pillars of Heaven shake. Yeah, Jack Burton just looks that big ol' storm right square in the eye and he says, "Give me your best shot, pal. I can take it."
I'm really surprised that no one has mentioned the Mack from The Road Warrior, I would think that would be a fairly straight forward build with the AMT Mack R and Revell tanker. Of course there would be a fair amount of scratchbuilding involved and you would need to make it a righthand drive to be completely accurate.
There are diecast and resin GMC Cannonballs out there so you could do the truck from the 1950s TV show Cannonball.
