Donner as director. Superman II was also a box-office hit, grossing $108 million in the United States. Through her appearances in the Superman films, Kidder maintained a close friendship with her co-star Christopher Reeve, which lasted from 1978 until his death in 2004: "When you're strapped to someone hanging from the ceiling for months and months, you get pretty darned close," Kidder told CBS. "He was such a huge part of my life... He was complicated, very smart, really smart, and he knew he'd done something meaningful. He was very aware of that and very happy with that role." Also in 1980, she appeared in Paul Mazursky's romantic comedy Willie & Phil, playing one-third of a love triangle opposite Michael Ontkean and Ray Sharkey. 1981–1988: Career re-evaluation Kidder starred in the Canadian comedic road movie Heartaches (1981), portraying a free-spirited woman who helps an acquaintance raise her child. Vincent Canby of The New York Times noted: "Nothing happens in Heartaches that isn't telegraphed 15 minutes ahead of time, but Miss Kidder and Miss [Annie] Potts are good fun to watch, not because they convince you of the reality of their characters but because they handle their assignments with such unbridled, comic, actressy enthusiasm." She then starred opposite Richard Pryor in the comedy Some Kind of Hero (1982), about a Vietnam War veteran who attempts to re-assimilate into civilian life. While filming the picture, Kidder stated she "fell in love with Pryor in two seconds flat," and the two carried on a relationship during the production. Prior to this, Kidder was romantically linked to Canadian prime minister Pierre Trudeau in the early-1980s. In 1982, she appeared in a stage performance of Bus Stop, playing Cherie opposite Tim Matheson as Bo, which was broadcast on HBO. It was reported that, as a result of Kidder's previous objection to Donner's directorial replacement for Superman II, her role in 1983's Superman III was notably small, consisting of 12 lines and less than five minutes of footage, though the producers have denied this in DVD commentaries. The same year Superman III was released, Kidder also starred as a court stenographer-cum-private eye named Mickey Raymond in the comedy Trenchcoat (1983). Critic Roger Ebert disliked the film, deeming it "one of the most tired, predictable, uninteresting movies in a long time." Also in 1983, Kidder produced and starred as Eliza Doolittle in a version of Pygmalion with
