The parade of stars continued on day 4 of the Toronto International Film Festival as Steve Carell, Nicholas Hoult, Deepa Mehta, Julianne Moore, Ellen Page and Kristen Stewart hit the streets for splashy red carpet premieres.

Here's a look at some of the festival highlights from Sunday:

Music-obsessed Quebec director Jean-Marc Vallee says he's looking forward to tackling his first straight-up rock 'n' roll feature – a potential biopic of Janis Joplin starring Amy Adams.

The project has long been kicking around Hollywood – both Fernando Meirelles and Lee Daniels were previously attached – but has failed to get off the ground.

While on the circuit with festival opener "Demolition," the Montrealer said he was waiting for the project to be officially green-lit, but added that Adams has already begun singing lessons.

"We had conversations. We went to the Janis Joplin vault in L.A. but we haven't started the official work yet," Vallee said.

Adams will sing herself in scenes recounting Joplin's days as a folk singer, but will lip sync when it comes to the rock 'n' roll years.

"Nobody can sing like Janis. There's no way, it's impossible," Vallee said. "You need to lip sync. Amy Adams will not try to pretend to sing like Janis Joplin."

Idris Elba says he hit the turntables on the Spanish island Ibiza to shake off his warlord character in "Beasts of No Nation."

"I couldn't have done anything more different. Like, literally 48 hours ago I was in a jungle in Ghana and now I'm (DJing) in a night club," the British star told reporters.

"I did that on purpose, actually, because character residue -- which sounds like a psychological term that I've been diagnosed with -- but character residue is a big thing, it's real, for me."

"Beasts of No Nation," directed by "True Detective" Emmy winner Cary Fukunaga, stars Elba as a charismatic yet ruthless commander of mercenary fighters during a civil war in an unnamed West African country.

The story is based on the acclaimed novel by Uzodinma Iweala of Nigeria.

"With this character, it was really easy to shake, if I'm honest," said Elba, who won a Golden Globe for playing a detective on the British TV crime drama "Luther."
