Glen Powell has warned Hollywood has become even more difficult for "struggling" actors

He told Vanity Fair magazine's Hollywood issue: "That's the other interesting thing about this business right now-how much it's changing. The business no longer supports struggling actors the way it did when I was kind of coming up. I would do an episode of 'NCIS', and that would keep me afloat for a year. You know what I mean?

"My overhead's not high. You're not living a lavish lifestyle. You're hiding a flask in your boot if you go out for a drink. You're not necessarily able to afford anything significant in that town, but you are able to stay there.

"Those little jobs, like getting a commercial, keep life in the system."

One such job for Glen was playing a stock trader in 2012's 'The Dark Knight Rises' and he will "never forget" how it felt walking on set for such a high-profile movie and how "validated" he felt when cast by director Christopher Nolan.

Asked what he remembered about the film, he said: "I remember everything. You never forget the feeling. It's something I carry to every set I walk on now, which is just the reverence for being on a set in general.

"But I remember on 'Dark Knight Rises' the feeling of being able to walk onto a set and you knew everybody in the world wanted to be on that set, right?

"Even though it was a small role, I auditioned several times for it. I was getting to work with the greatest director on the planet, Christopher Nolan. And you're sitting there and all of a sudden Tom Hardy walks in as Bane. It's electric. It's sort of out-of-body.

"That was one of those movies when nothing was going on in my life. I was just fighting for every inch.

"And when Christopher Nolan casts you in his movie, it's a validation that's hard to explain.

"And I've talked to Chris about this. We've run into each other at different things. I saw him during his amazing 'Oppenheimer' run, and he's very proud that he plucked me early. I'm just very grateful that he took a shot."
