Though the film series is already in its third week, there are still five more chances for film buffs to watch classic Alfred Hitchcock movies on the big screen. The Collins Center for the Arts in Orono will screen a Hitchcock film on Sundays through March 20. They’ve already shown “Psycho” and “Frenzy,” and this Saturday at 7 p.m. the CCA will screen “Rear Window,” the mesmerizing suspense classic starring James Stewart and Grace Kelly. Other films include the lesser-known “Topaz” on Feb. 6, “Vertigo” on Feb. 13, “The Trouble With Harry” on March 6, “Torn Curtain” on March 13, and “The Birds” on March 20 — all at 7 p.m. Admission is $6.
