Glenda Jackson's Best Actress Academy Award win for this movie was so shocking to viewers of the ceremony that a recount was considered for the votes. The Oscar was rumored to be going to Marsha Mason for 'Cinderella Liberty' (1973) or Ellen Burstyn for 'The Exorcist' (1973) as they were the front runners.
The black-and-white film on television that George Segal and Glenda Jackson were weeping to when watching it, was David Lean's 'Brief Encounter' (1945). In that film, the main characters, who were both married but not to each other, were also having an affair. 'A Touch of Class' (1973) was first released about twenty-eight years after 'Brief Encounter' (1945) had premiered.
Glenda Jackson was not present at the Academy Awards Ceremony when she won her Best Actress Oscar for Um Toque de Classe (1973). The film's writer-director-producer Melvin Frank accepted the gong on her behalf. Um Toque de Humor (1979) was the pair's first cinema movie collaboration since Jackson's Oscar win for Best Actress in a Leading Role
Actor George Segal replaced actor Roger Moore in the leading man role of Steve Blackburn. Moore withdrew from acting in the production in order to star in his first James Bond movie 'Live and Let Die' (1973). However, Moore was still involved with the production of the picture, in the form of being an uncredited executive producer on the movie.
Glenda Jackson won her second Academy Award for this film. Jackson had won in the same category of Best Actress in a Leading Role about three years earlier for 'Women in Love' (1969). Jackson was not present at either ceremony. Juliet Mills accepted the award on her behalf for 'Women in Love' (1969) whilst writer-director-producer Melvin Frank accepted the award on her behalf for 'A Touch of Class' (1973).
