Valiant (2005)

Continuity mistake: When Valiant flies down the gun barrel, he takes off his backpack and helmet, and he lays them down in the barrel before squeezing through the back of the gun. When he comes back out through the gun with the other birds, the backpack and helmet are not there.

Plot hole: How can Valiant have such a hard time lifting the key to rescue Bugsy but easily knock the missiles down, lift the clippers, and push down the lever in the mill?

Valiant: It's not the size of your wingspan that counts, no, it's the size of your spirit.

Bugsy: I've been shanghaiiiied.

Von Talon: I'm a vegetarian.
Mercury: And yet you wear a leather cape.
