As Hollywood stars go, he is one of the biggest while she is one of the brightest rising.

Keanu Reeves and Lily Collins dropped into Applegate’s Deadline Hollywood Studio at the Sundance Film Festival on Saturday to chat about their upcoming film.

In To The Bone, Lily plays Ellen, a young girl battling anorexia.

Reeves meanwhile plays Dr William Beckham, an unconventional physician who challenges her to face her condition and embrace life.

They were joined by the film’s director Marti Noxon, who also wrote the film, based on her own battle with the eating disorder when she was young.

Noxon – making her directorial debut – was a writer and producer on Buffy The Vampire Slayer, and currently exec produces Code Black and Girlfriend’s Guide To Divorce.

Also on the couch was The Good Wife star Carrie Preston, who plays Lily’s stepmother.

The film is an official selection of the U.S. Dramatic Competition at the 2017 Sundance Film Festival.

Keanu fans are also eagerly awaiting Chapter 2 of his John Wick franchise, set for release next month.

In the sequel John is forced out of retirement once more by a former associate plotting to seize control of a shadowy international assassins’ guild.

Bound by a blood oath to help him, he travels to Rome where he squares off against some of the world’s deadliest killers. 

Lily meanwhile, fresh off her Golden Globe nomination for her turn in Rules Don’t Apply, is also set to appear in Okja and Halo Of Stars this year.
