Update: Looks like all the free tickets to Ghostbusters have already been claimed, however, you can still attend the free community event at Fenway Park beforehand. Update #2: I have seen tickets since my last update, so you may want to pop on occasionally to see if anything comes up. Good luck!
Hi-Chew is sponsoring a movie screening of Ghostbusters at Fenway Park on Thursday, October 30th, 2014. Gates open at 6pm and movie starts at 7:15pm. Tickets are free but you do need to request them here.
There is also a free community event beforehand from 3-6pm with trick-or-treating around the warning track.
