Liam Neeson is wary of accepting roles in films similar to 'Taken'.

Neeson, 62, has enjoyed huge success with the 'Taken' franchise, which sees him play the role of a retired CIA operative, but the Irish-born star admits he was initially reluctant to accept a role in new film 'A Walk Among the Tombstones' because he thought it was too similar to 'Taken'.

He explained to Empire magazine: ''When I first read Scott's [Frank, director-and-writer] script, I hesitated. Because I thought, 'Here we go, here's another [expletive] telephone call, talking to the bad guys.' So there was this huge question mark before taking it on.''

Neeson said that unlike some of his co-stars - who took to listening to strange music in preparation for their roles - he finds it easy to tap into the film's dark mentality.

He added: ''I knew what was required and I can easily access that kind of darkness, you know.''

'A Walk Among the Tombstones' also features 'Very Good Girls' star Boyd Holbrook and Dan Stevens, who appeared in 'Dowton Abbey' until 2012, and will open in cinemas on September 19.
