The observation tower at the Sugarloaf State Reservation is being used as a set for ''Edge of Darkness,'' an upcoming film starring Mel Gibson.
Visitors to the summit, as well as passersby, can see a construction crew working to turn the tower into Hollywood's version of an observation tower. Production crew workers began erecting a 40-by-60-foot building on the east side of the tower's base just after Labor Day.
