Una hora decisiva

The Cupcake Palace, at least the exterior, appears to have been filmed at the Sub Zero ice cream store at 62 Center Street, Provo UT.

At the beginning of Act III, Trish and Piper accidentally bump into each other in bakery which destroyed their cookies for competition. Trish sits down in despair. Camera moves to show only her and she holds her left hand on head. Then camera shows wide shot with all of tree them (Trish, Piper and Katie), but Trish doesn't hold her hand on head any more. Then camera again shows only her at close shot, and hand is again on her head. Then camera moves at wide shot again, and Trish doesn't hold on head again. This happens several times in quick succession, and it's funny how sloppy was done. They obviously have two different shots merged into one.
