While the actress covered up on a snowy evening in a sparkling floor-length gown and fur coat, the activists scrawled political slogans over their naked breasts.
The semi-naked women appeared shortly after 74-year-old Fonda whisked through the doors in her sequined gold dress, metallic clutch bag and strappy sandals.
After she had given the peace sign to photographers as she showed off her picture perfect smile, the Femen protesters took things a step further.
Oleksandra Shevchenko, one of a trio of demonstrators, told Interfax the group were trying to draw attention to the barbaric practice of genital mutilation.
‘One girl is circumcised every 19 minutes,’ she said.
But they failed to time their appearance to coincide with that of the stars at director Wong Kar Wai’s biopic of Yip Man, mentor of kung-fu king Bruce Lee.
The women were quickly removed by security and kept in a police vehicle for about an hour, according to Shevchenko.
Femen are known for staging attention-grabbing topless protests, at big events including major football matches.
The opening night premiere of martial arts film The Grandmaster was also attended by stars including Alina Levshin and Aylin Tezel, dressed more modestly in black.
