When Hilary Swank turned up on this list, it was inevitable that Julianne Moore would soon follow. The lookalike actresses have a running joke about sharing jobs and having similar careers, so of course Moore has played a gay character on screen as well! In fact, she's done it several times over, but the pick of all of her gay and bisexual roles is probably Jules in 2010's 'The Kids Are All Right,' which saw her nominated for a Golden Globe.
The movie is a comedy-drama but is especially notable for being the first mainstream movie that depicted a same-sex couple raising children. We've come a long way in the past decade! Moore's character in the film is a bored housewife who starts an affair with a male gardener, which is a nice twist on the old stereotype. Various publications, including The Independent newspaper in the UK, named it as the best film of 2010.
