John Travolta turns 70 this Sunday. The actor has faced three tragedies that have marked his life.

The seventies of the last century were his peak moment, thanks to the two films for which he will go down in posterity. He insisted that it be Olivia Newton-John who played the sweet Sandy, a high school girl at the time 28 years old in Grease. They raised more than $350 million. “When you share a success as meteoric as that, impossible to surpass, there is a bond that always remains,” he said.
