Born in Kansas to, Marjorie, a lifeguard instructor and Jay Hopper, an OSS agent; young Dennis developed an interest in acting which eventually brought him to the Actors Studio in NYC. Hopper eventually turned his hand to photography, painting, poetry, and art collecting. One of his photographs became an album cover for Ike and Tina Turner and he purchased one of Andy Warhol's early prints of Campbell's Soup Cans for $75.

Audiences were treated first hand to what was going through his's mind at this time by the almost incomprehensible film The Last Movie, dismissed by both critics and audiences in 1971. Hopper sustained his Hollywood lifestyle by appearing in many low-budget movies until landing perhaps his most perfect role in Francis Ford Coppola's Apocalypse Now. It is widely held that Hopper, an avid photographer, was not really acting as he portrayed a manic hyperactive photojournalist.
In the early 1980's Hopper entered rehab to kick his 3-grams-a-day cocaine addiction washed down by 30 bottles of beer and marijuana spliffs. It may have taken a while but it seemed to have worked by the time he played Frank Booth in David Lynch's Blue Velvet. He was back on form and his career revived.
Hopper directed Robert Duvall and Sean Penn in the acclaimed police drama Colours in 1988 Just two years later studio executives butchered his 1990 Jodie Foster film Catchfire - forcing him to use the Alan Smithee [disowned] credit and causing him to lose his taste for direction.

Hopper was delighted to have completed his work on Crash's second season as well as editing a 546-page book of photographs taken by him. Hopper was honored with the 2,403rd star on the Hollywood Walk of Fame, in front of the iconic Grauman's Chinese Theater on Hollywood Boulevard. Surrounded by friends including Jack Nicholson, Viggo Mortensen, David Lynch, Michael Madsen, family, and fans, he attended its addition to the sidewalk on March 26, 2010.
Hopper is survived by his fifth wife Victoria Duffy [from whom he had filed for divorce], 42 with whom he had a 6 year old daughter. May he rest in peace.
