Toronto International Film Festival is still underway and Rachel Weisz has become another star who showed up at the TIFF BELL Lightbox venue to promote "The Deep Blue Sea". Coming without the companion of hubby Daniel Craig, the "Mummy" beauty was joined by co-star Tom Hiddleston at the event which took place on Sunday, September 11.

Donning a long dress, Weisz was all smiles when being pictured alongside Hiddleston who put his arm on her waist. The actor, meanwhile, looked sharp in a black and white outfit while tagging along his wife to the special screening. Director Terence Davies was also present to support the event.

Earlier in the same day, Weisz and Hiddleston who play a couple in the movie hit the Variety Studio At Holt Renfrew where they had interviews with reporters. The 41-year-old British actress wore a Giambattista Valli dress for the occasion while the "Thor" actor opted for a casual shirt.

"The Deep Blue Sea" is set in the 1950s London where Weisz's Hester Collyer leads a privileged life as the beautiful wife of high court judge Sir William Collyer. To the shock of those around her, she walks out on her marriage to move in with young ex-RAF pilot, Hiddleston's Freddie Page, with whom she has fallen passionately in love.

Starring also Simon Russell Beale as Weisz's on-screen husband, this period drama still has no U.S. release date.
