Harrison Ford is still readying himself to star in the long-awaited Indiana Jones sequel, despite his concerns over the script. The veteran actor has been waiting for years for George Lucas and Steven Spielberg to find a suitable script for Indiana Jones IV. The last movie, Indiana Jones And The Last Crusade, was released in 1989.

And while Spielberg insists filming will begin this year, Ford admits he is worried about the script.

He tells British film magazine Empire, "If you find out when it's starting, let me know. The reason it hasn't happened yet is we haven't had a good enough script. (Is the) script ready? I think that was a different script... it looms. (M. Night Shyamalan was writing the script) and I think we lost him through the failure of George and Steven to attend to him, which is a real shame."

The filmmaker is set to direct the movie, with Lucas producing.
