"Bridget Jones meets Godzilla" might be the fantasy movie pitch that's often gone through your head during boring office meeting reveries, but it's also now a real thing - and it's surprisingly the buzz of the Toronto International Film Festival this week.

Colossal, a new monster movie by Spanish writer/director Nacho Vigalondo, starring Anne Hathaway and Jason Sudeikis, has been earning raves (and seven-figure buying rights) since premiering in Toronto, and not just due to its bonkers plotline, which sees Hathaway playing Gloria, a boozy online writer who moves back home after losing her job and being dumped by her boyfriend, all while a giant tree monster terrorises South Korea.

Rather, viewers are praising the film's timely attack on toxic masculinity and male entitlement.

"Watching the movie, I was struck by what a brilliant example it offers in terms of why you shouldn't give hateful men great amounts of power," Hathaway, who was in the second trimester of her pregnancy during filming, said in an interview with Vulture.
