As for makeup, Jessica enhanced her porcelain complexion with peach blush and put on a glossy pink lip.

She was photographed stepping out of her chauffeured SUV just steps away from the Royal Alexandra Theater in Toronto, Canada.

Jessica was accompanied by two suited security guards as she made her way to the red carpet.

At the premiere, the Molly’s Game actress was reunited with her co-stars Peter Sarsgaard and Federica Garcia, as well as the film’s director Michel Franco.

Also in attendance were the film’s producers, Alex Orlovsky and Duncan Montgomery.

Memory marks Jessica’s first appearance since her Oscar-winning role in The Eyes Of Tammy Faye.

Memory premiered for the first time last week at the Venice International Film Festival.

In Memory, Jessica plays Sylvia, a social worker who leads a simple and structured life.

This is broken open when Saul follows her home from their high school reunion. Their surprising encounter will have a profound impact on both of them as they open the door to the past,” IMDB said.

Just a few days after the premiere of the film, it was announced that Jessica and director Michel will work together again on the film Dreams, according to Deadline.

Since July 17, Hollywood has come to a standstill when members of the SAG-AFTRA union joined the Writers Guild Of America to strike.

It led to growing concerns about the use of artificial intelligence and streaming residue.

According to the strike rules, the talent is prohibited from promoting films of the companies represented by the AMPTP.

However, many of the films debuting at TIFF are independent, which has led to a number of actors and actresses – including Jessica – signing interim deals that allow them to walk the red carpet and promote their films at the festival.
