JOHN TRAVOLTA considered quitting acting after the death of his son Jett from a seizure.

The Grease star admits the loss was almost too much to bear after the 15-year-old passed away while on a family holiday in the Bahamas in January, 2009.

The grieving actor was persuaded to return to moviemaking by director Oliver Stone for his latest film Savages after taking a break from the industry.

Travolta tells the BBC, "I lost my son a few years ago and I had, you know, been having quite a time of that and after three years of getting a lot of support from my church and a lot of support from people, fans, family, I decided it was okay to go back to work. Because I had even thought about retiring at one point, because it just felt like too much."
