Fifty years ago, a monumental movie premiered that forever changed Hollywood. Ben Mankiewicz talks with actors Richard Dreyfuss and Lorraine Gary and screenwriter Carl Gottlieb about filming the Steven Spielberg blockbuster.

National Geographic’s new documentary “Jaws @ 50: The Definitive Inside Story” directed by Laurent Bouzereau gives a behind-the-scenes look at Steven Spielberg’s iconic 1975 shark movie with rare archival footage and interviews with conservationists and famed directors.

Ahead of the 50th anniversary of the release of 'Jaws,' we take a look at some of the issues that plagued the film during production.

Heart-pounding doesn’t even begin to describe the last 15 minutes of “Jaws.” For those who haven’t seen it, or repressed the memory, I won’t reveal it here. But safe to say it’s one of the most suspenseful and hair-raising endings ever put on screen.

Just when we all thought it was safe to go back into the water, Jaws returns to celebrate its 50th birthday. Released in 1975, Steven Spielberg’s breakout film endured a hellish, high-seas production involving a constantly broken shark and a frequently drunk Robert Shaw.
