The 1961 film West Side Story will be playing in selected movie theatres, nationwide, including the Greater Boston area. It will be aired on Sunday, June 24th, and on Wednesday, June 27th. Tickets can be purchased at the box offices of any of the selected movie theatres, or online using fathom events.com, fandango.com, or even on amazon.com.
The more people purchase tickets for this great, golden oldie-but-keeper of a classic movie-musical, the better it will be for this film. Hope I've been of some help here.
