A heads up for those that might be interested... The relationship between Boston and Hollywood is the topic of a new class at the Boston Center for Adult Education called How Hollywood Works: Getting Into the Movies, which meets Feb. 4, 11 and 18. Charles Hoyt, who is teaching it, knows his stuff--he's even showing an episode of Route 66 that was shot in Boston during the first class. Depending on my schedule, I may be joining him during that meeting. Guests at other classes come from such places as the Mass. Film Office and Emerson College.
