Super Freak
In Commando - when Arnold loads up & heads to the big bad's digs on the island to rescue Alyssa Milano.
As he starts throwing grenades at the goons - if you slow those scenes down, you see little spring loaded platforms catapult those guys in the air to simulate impact from the explosions.
Also - same film, the 'Sully' car chase in his yellow Porsche. Arnold rams him & wipes out the panels on that side.
Next shot - the damage swaps to the other side!!
Classically funny.
Don't forget the one scene in commando where Arnold is dangling onto the bad guy by his leg off a cliff but you can clearly see a strap holding the guy.
