Robert Pattinson has admitted he could "genuinely be retiring" after wrapping his 'Batman' trilogy

And the 'Twilight' star - who kick-started his career at the age of 17 playing Cedric Diggory in 2005's 'Harry Potter and the Goblet of Fire' - has now admitted he may bid farewell to acting when he wraps the third flick.

Robert told The New York Times' Style magazine: "I could genuinely be retiring by the end of them.

"Not in a million years did I think I'd still be doing this when I got my first job. I can't believe this is still going."

The second film is not due to hit cinemas until 2026.

Admitting acting takes up a lot of "energy", he said: "The main thing is constantly remembering what your job is.

It's a discipline to not use your energy on anything other than that."

The 'Mickey 17' star has relished the opportunity to work as a producer after signing a production deal with Warner Bros and confessed he got tired of always playing the "English prince".

He said: "If you're just an actor, you don't really meet with anyone other than directors who want you to play an English prince.

"Doing this, I've met so many different people and I have something to provide them. It's made me more understanding of what I'm doing as a performer, as well."

Robert is best known for his starring role as vampire Edward Cullen in the 'Twilight' franchise and recalled a recent encounter with someone who thought he stopped acting after the cult classic saga.

The 'Tenet' star - who became a father for the first time this year after fiancée Suki Waterhouse, 32, gave birth to their daughter - recounted an immigration officer asking him: "'Hey, you're the guy from Twilight. Why'd you stop acting?'"

His hilarious response was: "I was like... 'I'm Batman?'"

Robert recalled: "She just laughed."
