The Hangover would appear to have a good shot at staying at the top of the box-office for a third consecutive weekend -- particularly since it’s the kind of movie families are likely to take dad to see on Father’s Day. Its strongest competitor, it would seem, is the romantic comedy The Proposal, starring Sandra Bullock and Ryan Reynolds, which might be more appropriate for Mother’s Day. Box office prognosticators figure that each of the films should take in around $20 million. Also opening is the Jack Black comedy Year One, which is expected to take in something short of $20 million. Given Sunday’s day with dad, it’s likely that Disney/Pixar’s Up will remain a strong contender as well. While none of those films is likely to take in blockbuster bucks, their combined revenue could very well lift the box office back into the win column after three losing weeks versus last year. Also opening in limited release -- New York and Los Angeles -- is Woody Allen’s latest comedy, Whatever Works, starring Larry David.
