Well...
I would suggest trying to avoid making four out of five questions about actors and actresses. If you are going to make a Sweeny Todd test I would suggest some questions not relating to the movie just released.
Sweeny Todd was a ficticous (or at least I hope so) 18h century barber/serial killer created by Peter Haining.
Just off the top of my head, here are a few questions you could add.
1.) Who was Sweeny Todd created by?
2.) Who created Sweeny Todd?
3.) Why do Mrs. Lovett's pies taste so horrible?
ect. those are pretty bad examples, but I woke up at 5:30 this morning and its approximately 6:30.
good luck on your test.
