French media say several interviews with actors from the movie have been canceled, however, including with Jean Dujardin and Louis Garrel.
The French daily Le Parisien on Friday reported claims from a French woman in her early 60s that she was assaulted at age 18 in 1975 by Polanski at his chalet in Gstaad, Switzerland.
Polanski "firmly contests" the allegation, his lawyer said.
Polanski has been a fugitive from the U.S. for more than four decades since pleading guilty to a sex offense.
