Mel Gibson temporarily quit acting after starring in SIGNS - because he felt like a "ham-fisted dinosaur" on the set of M. NIGHT SHYAMALAN's 2002 movie.
The movie star has spent eight years refusing to step in front in front of the camera because he had such an unpleasant experience making Signs.
Gibson tells the Los Angeles Times that Shyamalan made him realise he needed to take a break to hone his craft.
He explains, "I felt ham-fisted. He (Shyamalan) told me I was just doing too much. I looked around... and I was the oldest guy on the set and I felt like the least sophisticated. I decided I needed to rethink everything.
"I got into this... because I wanted to be good. I walked away because I don't know that I was bringing much new to anything.
"Another seven or eight years of living informs the choices one makes."
