Last week the Orson Welles showed Hitchcock's single greatest movie, Strangers on a Train; this week, they're showing his two greatest movies, The Lady Vanishes and The 39 Steps. If you're one of the masses who'll be leaving Cambridge next week, hit the Orson Welles--you may have thought that Harvard and MIT were Cambridge's greatest resources, but you're wrong. Without the Welles, Cambridge would be a hole.

McCabe and Mrs. Miller. You may react like Warren Beatty, who was pissed at Altman for smothering all his lines with wilderness noise and human babble. Or the scenery may get to you--fog and snow turning into literal shrouds, raw timber buildings sitting squalid like open wounds in the woods. It's a movie that jello-quivers your mind--the death scenes just kinda fester up there afterwards, shake, rattle, and roll. Choose your poison.

The Do-It-Yourself Animated Cartoon Film Program. Ever wondered what was on the other side of Central Square besides the MIT geeks with pocket computers and the NECCO factory? Well, there's a little hole in the wall up Main St. from Central Square that shows movie shorts anb animations. They're called Off the Wall, and in living memory they've never failed to string together anything less than brilliant shorts. It's a coffeehouse-art gallery with a screen up in the corner, and the subway rumbles underneath every 20 or so; and what with the various exotic tea smells, it's all very dagguerotyped. Don't flee Cambridge before you check this out. Call 354-5678 for information.

The Harder They Come Now that reggae has made the cover of the Rolling Stone and is no longer the exclusive province of the chic, maybe this Jimmy Cliff "country hick to shantytown to bigtime to rubout" regional novel of a flick will make it beyond the cult who love it already. You can see it if you really want.
