Seven Days in Utopia
(2011)

The great golfer, Ho, misses his 8 foot putt, giving Luke (Lucas Black) a chance to win if he makes his putt.  Luke uses the putter that Johnny (Robert Duvall) gave him.

The movie ends as the putt goes toward the hole, and then gives a web address to find out what happens:  didhemaketheputt.com.  (Yes, he did.)

Thanks Susan!
