Narrative:
Flying the williamsport arrival into newark. Nyc cleared us to descend from 31;000 to 25;000 just past slt. As we initiated the descent we entered the wake turbulence of a preceding company B777. The aircraft rolled right to 35 degrees of bank. The autopilot disconnected and bank angle was announced over the speakers. The flying pilot recovered the aircraft to normal flight parameters and the autopilot was reengaged. We queried nyc as to what type aircraft we were following and advised them we encountered wake turbulence. We were then given a 2 mile right offset for the remainder of the arrival.
