She was known to perform both comic and dramatic roles, such as Gilles Carle's The Death of a Lumberjack (La Mort d'un bûcheron) in 1973, André Brassard's film version of Tremblay's Once Upon a Time in the East (Il était une fois dans l'Est) in 1974, Denys Arcand's Gina in 1975, Claude Fournier's Far from You Sweetheart (Je suis loin de toi mignonne) in 1976, Fantastica in 1980 and Carle's The Plouffe Family (Les Plouffe) in 1981, playing the tormented Cécile.
In 2002, she produced a new comedy fantasy, Alice's Odyssey (L'Odyssée d'Alice Tremblay), which received a lukewarm response from critics and moviegoers.
[citation needed] In 2003, taking advantage of the success of her motion picture characters, Filiatrault produced a television miniseries for TVA, Le Petit monde de Laura Cadieux (2003), before tackling a new film Bittersweet Memories (Ma vie en cinémascope) (2004), a dramatic biography of 1930s-1950s singer Alys Robi (played by Pascale Bussières).
As artistic director of the Théâtre du Rideau Vert, she and the theatre were criticized in January 2015 by a coalition of Montreal arts groups for a year-end production in which a Caucasian actor portrayed hockey player P.K.
Filiatrault responded that she was "shocked, outraged, and humiliated" by the reaction, saying that she had been in show business for 60 years and was the first person to hire a black Quebecer on television.
