ongoing-Feb. 18

Do ya like sitting on your bum? Do ya like eating popcorn? Have a bit of post-holiday free time? And, primarily, do ya like movies, all kinds of movies? How would you like to participate in a fundraiser that will benefit the Brattle Theatre? The Theatre is holding its second annual "Brattle Watch-A-Thon Fundraiser" through Feb. 18. There's no special programming for this stretch - except at the end. What you do is go to as many of the 20 or so regularly scheduled films - a Robert Altman series, a romance block - as you can - having raised pledges from pals, a la any charity marathon - and pay a $50 registration fee. (You get this back if you raise a grand or more.) Also: You can watch movies at other theaters and can credit (half credit actually) by bringing the ticket stub to the Brattle. It begins to end Feb. 17 with a 12:30 p.m. start to the Brattle's annual "Schlock Around the Clock" stretch, which concludes at 9:30 the following night. Prizes include all kinds of neat stuff from Harvard Square businesses - two biggies for the person who sees the most movies and another for the person who raises the most dough. Prizes will be announced shortly. Check Brattlefilm.org for details. Last year, the theater brought in $10,000 and hopes to beat that this year. Whose idea? "Just a brainstorm amongst our office," says Brattle top dog Ned Hinkle.
