Visible crew/equipment: When Shane is talking to Mrs. Plummer before she leaves, throughout the scene the camera man is reflected in her window (he is in black, not to get confused with Shane's white shirt) and as the car drives away the camera is shown backing up in the black door.
Revealing mistake: When Shane is fighting the two ninjas, they are armed with expandable batons, which are tubular hardened steel. During the fight sequences you can see the plastic batons bending repeatedly.
Question: Shane tells Lulu a story about a family of elves that's a little obscure. Is it just meant to be another demonstration of Shane's obsession with military action, or is the story based on anything?
