[8] In 1987, Graham created the 8-minute[9] video Apocalypse Pooh, considered by many to be one of the earliest examples of a mashup video as it combines footage from Disney's Winnie the Pooh shorts (each directed by Wolfgang Reitherman, released between 1966 and 1977[9]) with audio from Francis Ford Coppola's 1979 film Apocalypse Now.

[10][2] While his video works went underappreciated at art schools in his own country, they were received better in the US to the point of being shown in New York City's The Kitchen.

[2] Scott Mackenzie of CineAction wrote in 2007 that the film was exemplary of the new avant garde, "a potent synthesis of the radical politics of the 1960s and 1970s with character animation Hollywood cinema at its most surreal and uncanny" as a vehicle to examine the "horror and allure [of the Vietnam War] in mainstream cinema".

He also noted that the film came at a time when "barriers between media were disintegrating" and called it "the godparent of today's mash-ups".

The film is considered an underground cult movie whose reputation is based solely on the depth and scope of the bootleg video circuit.
