The cart can be picked up if Frank leaves one area of the mall pushing the cart and the load screen appears. When the new screen is loaded, Frank will be holding the cart instead of pushing it.
The cart can be picked up after Frank kicks the cart.
The cart can be picked up if it is pushed off balance or tipped on its side, or other ways other than kicking. The most difficult way is to hit the cart and then push the cart off balance, with a light damage weapon. This is difficult to do and Frank may destroy the cart.
The modified spray bottles have "It is hell without Jesus" written on them.
In the game, there are not as many cleavers as shown in the cutscene.
The Weapon Cart was referenced in "Ultimate Marvel vs. Capcom 3", as Frank uses an improved version, his having chainsaws instead of cleavers. There is also a dead zombie sitting inside the cart to, just how Isabela was during her capture.
