Harrison Ford will make a fifth 'Indiana Jones' movie if he's "still alive".

The 67-year-old actor - who has played the daredevil archaeologist in all four movies of the action-adventure franchise - would definitely be interested in reprising the role as long as the story is ready quickly.

If we find a script and develop a story in less than the 18 years it took to make the last one, if I'm still alive, I'll make myself available.

 Harrison - who worked on all the previous films with George Lucas and Steven Spielberg - said: "If we find a script and develop a story in less than the 18 years it took to make the last one, if I'm still alive, I'll make myself available."

Although famous for his action and sci-fi roles, the 'Star Wars' star is open to lots of different roles nowadays, and joked he would even consider playing a woman.

He quipped to Empire magazine: "I have never played a woman. I have never played a fish. I would like to play a female fish - just because of the costume."

Harrison needs to keep his work fresh, otherwise he gets very bored.

He said: "I never wanted a real job. If I did the same thing over and over again I would just get bored p**sless. That's why I do a lot of things.

"I become involved in something because I have an emotional relationship with a story. I don't have ambitions to play a certain type of character, or be in a certain kind of movie. I have an ambition to be useful in the process of telling the story I have come across."
