Environment - Non Weather Related; Human Factors; Procedure
Shooting FMS Bridge Visual 28R SFO; called B777 in sight at beginning of approach. He was low and ahead for [Runway] 28L; wind was tail wind blowing toward B777. [We] discussed wake; at about 1;800 FT we commented on how it looked like he was heading in front of us for [Runway] 28R and how at night with no depth perception this was dangerous when we noticed him turn hard left. He had overshot [Runway] 28R and was in fact turning in front of us; we immediately got a 40 degree left wing dip and added power and recovered ending back on V-path; speed and course guidance. We were above 1;000 FT with wind blowing away from us to the B777 [so we] chose to continue.
B737 Captain reported wake vortex encounter in trail of a B777 on approach to SFO.
