Sylvester Stallone still gets worked up over the perception that he is a thuggish actor with no more strings to his bow.
The Hollywood action veteran – who was nominated twice for Oscars and Baftas for Rocky and has written more than 20 films and directed eight – revealed his frustrations during a 90-minute question and answer session with Jonathan Ross.
"It depends what day of the week it is. Sometimes it doesn't bother me, the next day I'm like, 'Where do they live'!" he told the audience at the London Palladium.
"All of the Rockys I wrote every word, but still people assume you are Rocky.
"One day I think I've got it together, the next day I want to kill everyone."
The lack of recognition is not limited to film critics, though – even his current Grudge Match co-star Robert De Niro seemed to take a dim view of his abilities.
He recalled: "We were doing a scene and I said, 'Bobby, is it me or do you feel the same way? The first time I'm doing a scene with you I think you're terrible'. And he said, 'I thought you sucked too'."
The two are great friends, but it is the British connection in his successful Expendables franchise who Stallone admitted is his current favourite.
He also revealed that in the third film, due out in August, Jason Statham might finally take a knocking.
"You may see history made in the next Expendables. I actually believe there's a bloody nose on the horizon," he said.
"We have a great rapport together. He's very straight, but when he smiles, when he jokes around, he's good."
Post-production on Expendables 3 is filling in the days for 67-year-old Stallone at the moment, but he has left the door open for a return to his iconic roles.
"I'd love to do another Rambo, but maybe if he works in Las Vegas," he joked. "Maybe it's run its course."
