While the 'Taken 2' star loves his evolution into an action star, the 60-year-old said he sometimes struggles with the stunts, reported Daily Star.
"It has started to hurt. The knees squeak quite a lot. I'll do stunt work until my knees give up. In the interim I love making these movies because it appeals to the little boy in me," he said.
Neeson tries to keep fit in his everyday life so that filming takes less of a toll on him but its still tough.
"Although I keep pretty fit otherwise but there's a considerable amount of fight choreography, training and rehearsing. Particularly in the last encounter scene we have in 'Taken 2'. It's not a superhero stuff. It's ugly and violent and tiring," he added.
