The bodyguard caught up in the middle of the Robert F Kennedy assassination in 1968 has heaped praise on Emilio Estevez's new movie BOBBY, about the tragedy - he has already seen the film twice. REV ROSEY GRIER was assigned to take care of Kennedy's wife ETHEL on the campaign trail as the Senator fought to become US President. He was standing just feet away from Kennedy when he was gunned down at the Ambassador Hotel in Los Angeles, and actually appears in footage taken on the night that Estevez used in his film. Grier admits he's stunned by the film and how realistic everything is: "I watched it and I was trying to get the pieces together... in each segment, where there was like an individual piece, that all came together. It was a puzzle. "It really impacted me when it all came together in the end. It was really dynamite. I had to hold myself together, because it was that powerful."
