Visible crew/equipment: During the "full attack" at the start of the Battle of Stirling Bridge, Wallace repeatedly shouts, "Hold," and in the wideshot right before Wallace finally shouts, "Now!" as the horses gallop towards the right side of the screen, we can see a white car at the left side of the screen. Viewed widescreen version. (01:27:15)
Visible crew/equipment: In the execution scene at the end, right as Wallace is being quartered, you can clearly see (on widescreen) a plastic spray bottle on the upper left part of the screen, presumably filled with fake blood.
Visible crew/equipment: At Stirling right before Wallace drops his sword and picks up an axe you can see some black duct tape on his sword. A man then swings his sword at the exact position of the duct tape. This is an obvious test take where they rehearse the scene, and was not meant to end up on screen. (01:27:00)
Visible crew/equipment: At the end of the wedding party scene, when the Scott shrugs off the English soldier who is taking his wife, you can see a spotlight covered with a blue tarp, behind his head. (00:23:55)
Visible crew/equipment: When Wallace captures the fort of the noble who killed his wife, he pushes said noble down a hill before putting him to the post and slitting his throat. If you watch when the noble is pushed, he rolls over and the cape uncovers the back of his costume. You can see blue pants that look like jeans under his costume. (00:45:40)
