The 'Killers of the Flower Moon' star spoke exclusively with ET backstage at the Palm Springs International Film Festival Awards Gala.
Though our heart will always go on for Leonardo DiCaprio, the 49-year-old Hollywood A-lister doesn't consider the fame and attention he receives during award season to be a part of his regular life off-screen.
ET's Denny Directo spoke with DiCaprio and his Killers of the Flower Moon director, Martin Scorsese, and his co-star, Lily Gladstone, backstage at the 35th annual Palm Springs International Film Festival Awards Gala on Thursday night, hosted by Mary Hart.
When the Titanic alum arrived at the glamorous event, he met with fans, giving his autograph and posing for pictures.
"Do I get used to it? It's not a part of my everyday life, but I was actually incredibly surprised at the turnout here," DiCaprio tells ET of greeting his admirers. "Palm Springs Film Festival's kind of going off. It really is."
Killers of the Flower Moon is already receiving critical acclaim at the start of awards season. The movie is nominated for seven Golden Globes, including Best Actor and Actress nominations for DiCaprio and Gladstone, respectively.
DiCaprio, 59, plays Ernest Burkhart while Gladstone plays his wife, Mollie Burkhart in the film, which follows the real-life story of the contract killings of several members of the Osage Nation by white men after oil was discovered on tribal land. Robert De Niro portayrs Burkhart's uncle, William King Hale.
"I feel like this was such an incredibly important story to tell. I know we went into the process with the utmost of care and we wanted to listen, and that was our job," DiCaprio says of making the film. "This was a dark chapter of American history, and we spent many years to try to tell this story right. We are very thankful, not only to the Osage committee for embracing us and telling us their story, but for all the actors, Lily included, to help shape the entire narrative of this movie."
Gladstone, a relative newcomer to the industry, says she had to put aside her own feelings of inadequacy and learn to trust herself to take on this role.
"I kind of lost the time to be nervous for feel any imposter syndrome because it was doing them a disservice in the work they were bringing," she says of DiCaprio and Scorsese. "I needed to bring as much to the table as they were."
As for whether she's gotten tired of her famous co-star and director amid the press tour for the film, Gladstone exclaims, "Oh, hell no!"
Killers of the Flower Moon will begin streaming Friday, Jan. 12 on Apple TV+.
