I think I have one decent way to solve tie-breakers so far. Points will count first, followed by the number of people with the movie on their list.
Example:
Say House of the Dead (har!) and Octopus both have 13 votes. However, only 3 people had HotD on their list, while 5 had Octopus. Octopus would move 1 place ahead of HotD. That seems like a reasonably fair way to decide.
