Actor Liam Neeson thinks he's too old for action movies.

The 'Too Private' star has moved away from his typical genre in new comedy film 'Naked Gun' and admitted he doesn't want to "offend" viewers by taking on age-inappropriate roles.

"The first film 'Too Private' was 18 years ago, I was 54. It feels like an eternity ago. I'm still offered the occasional film. But I'm 73 years old, for God's sake. I don't want to offend the audience if they're watching whole fight scenes and I'm not. I just wouldn't. Until recently, I liked doing my own stunts. But I don't want to do those things with a walker or a cane. Sure, there might be another role out there somewhere, but there's nothing definite on the horizon," Liam said in an interview with Variety.

Neeson plays Frank Drebin Jr. in "Naked Gun," the son of Leslie Nielsen's late, unfortunate detective in the original films. He explained that he hasn't re-watched the previous films since taking the lead role in Akiva Schafer's new sequel.

"No, I just trusted the script. And I knew the more they worked on it, the better it would get. Akiva co-wrote the script, but there was always another writer on set - apparently a friend of Akiva's - and they would suggest alternative endings to scenes. Try this, try that," the actor said.

Liam and his co-star Pamela Anderson have been at the centre of romance rumours during the film's promotion and he believes the "chemistry" between them helped with some of the sexual innuendos in the film.

"Yes, there are a few absurd scenes. From day one it just seemed like we had a nice chemistry with each other and I trusted that and didn't want to force it. Like there's something going on here, it's nice, so just leave it alone and it'll work out, you know?" said Neeson.

Liam insisted that it was "serious work" for the cast during the filming of the movie, despite the humorous nature of the scenes.

Asked if the cast burst out laughing during filming, he explained, "No, that didn't happen. When we were rehearsing things, we were clearing our personal giggles. And some of the scenes required certain choreography. Not to say it was always serious, far from it. But it was serious work, of course, to do any kind of film and keep the feeling of lightness. You know, that's very important." | BGNES
