Visible crew/equipment: Near the end of the boat chase, after the railing and Frank are pulled into the water but prior to the cut to Elise slowing her boat to allow Frank to board, a member of the crew can be seen exiting the cabin of Elise's boat. (00:05:50)
Visible crew/equipment: The morning after the police chase Elise asks Frank to tie off the boat. As Frank does this, you see a hairy male arm place a bag next to him. Elise is the only one on the boat so it's presumably her arm but when we cut back to her she's wearing a long sleeved sweater. They must have asked a crew member to stand in. (01:01:19)
Visible crew/equipment: When Elise is about to drive the boat towards chained Frank, a man pops up out of the boat. It can't be one of Shaw's hitmen, for they have not seen Elise's boat yet.
Visible crew/equipment: Right before they going to kiss you'll see the silhouette of a person in the back between them mirroring on the wall while the camera moves to the right. (01:33:02)
Visible crew/equipment: While Frank is on the rooftops, when Elise stares at him there's a huge crowd of people on the right watching the filming.
