Elisha Cuthbert doesn't think she has the "energy" to work on 24 again.

The 43-year-old actress played Kim Bauer, the daughter of Kiefer Sutherland's lead character Jack Bauer in the real-time drama but she admitted it wasn't an "easy" programme to work on because the shoots could be so "intense", and so if the show was ever to make a comeback, she's unsure if she'd return to the role.

She told People magazine: "It's hard to imagine, really, the scope of it. It was a whirlwind, too. I mean, the success of it all was overwhelming and thrilling and exciting.

"I have great memories of that time, but also, it was really intense too. We were working so much that the one-hour format... especially with all the action and all the intense night shoots, I mean, it was not an easy show to film.

"It was a well-oiled machine, but it still was a gruelling schedule. I don't know if I'd have the energy to partake in that again."

But Elisha praised 24 for being "amazing" and "groundbreaking."

She added: "So it was special to be a part of."

Elisha is still in touch with some of her former co-stars "on occasion", and she regularly runs into people who had guest roles in 24.

She said: "It's amazing how many actors were on that show.

"We may not have really worked physically in person together, but certainly a lot of actors pass through over the course of eight seasons, and so we have that in common."

While Elisha found working on the show to be demanding, Kiefer recently admitted he enjoyed his time on 24 because it gave him a "real job" with regular hours.

He told Fox News Digital: "I think 24 for me was a fantastic opportunity because it was the first thing that felt like a real job.

"I went to work five days a week, eight months to 10 months a year, and then I was lucky enough to do it nine years in a row.

"So, there was a moment where that made me feel calmer. But I'm back to the every three months I'm out of a job kind of thing."
