Hottest Brotherly Broods in Cinema
I hereby nominate the Pontipee brothers. Criteria: at least 4 brothers (3 if they're exceptionally studly) and actual relations. Which discounts, for example, Brad Pitt and Craig Sheffer in A River Runs Through It... Or the "Band of Brothers" (neither actual consanguineous siblings nor a cinematic fraternity). Or any number of hot frats depicted in teen comedies.
On a side note: I'm surprised that a near-classic film (some would grant it total iconic status for Kidd's choreography alone) has less than a page of comments.
