AMC Assembly Free Holiday Movies

Earlier, AMC Assembly held a contest, asking people to vote for their three most favorite holiday movies, which the theater would then screen it on a Saturday in December – if it won the popular vote, of course. The three most-voted movies, “A Polar Express,” “Home Alone” and “Elf,” will play for free at 9:30 a.m. on December 6, 13 and 20., respectively It’s the perfect way to get yourself in the mood for holiday shopping.

15th Annual Santa Speedo Run

December 6, Newbury and Boylston Streets

What started as a crazy idea among a few friends in December of 2000 has grown into one of Boston’s winter traditions. The Santa Speedo Run returns this Saturday, when brave souls clad in nothing but holiday accessories and speedos will take to the Back Bay for a scantily clothed sprint (or run, or jog) to the finish line, blasting Christmas music along the way.

Registration info can be found here; free for spectators.
