The original Rollerball (1975) is one of my absolute favorites. I have owned the LP Soundtrack, the VHS and now the DVD. The DVD needs more extras on it, though.
LOST PROMO CLIP
In 1975, there was a 15-minute promotional clip that ABC played at 10:45 PM at the end of a Movie of the Week. It was really good and it made me make the trek by bus to downtown Seattle to see the movie where I knew I could get in even though I was 15 at the time. (Did the same thing to see Blazing Saddles, 3 Days of the Condor, and a movie call Lipstick with the Hemingway sisters which really had a Joe Eszterhas feel to it.)
Perhaps, this is the "From Rome to Rollerball: The Full Circle" 8 minute clip that is mentioned at
http://www.imdb.com/title/tt0322340/ .
I'm also seeing a 2000 documentary called "Return to the Arena: The Making of 'Rollerball'" that I've never seen at
http://www.imdb.com/title/tt0310066/To have James Caan and Norman Jewison do a commentary while they're still able to would be priceless.
ROLLERBALL & WONKA: FILMED IN MUNICH
Interestingly enough, Munich was futuristic enough for Rollerball to be filmed there and "classic" enough for Willie Wonka to be filmed there a few years earlier giving it a Grimms Fairy Tales kind of feel.
GREAT POLITICAL DRAMAS OF THE 70s
I always think that the greatest film era of my lifetime was the 1968-1975 era that started with Bonnie & Clyde and 2001: A Space Odyssey, and ended with Jaws. This movie, along with 3 Days of the Condor, The Parallax View, Executive Action, and Soylent Green painted a look into dark forces at the levers of power that have made me a more conscientious seeker of information and perhaps less trusting of what I'm being spoon-fed.
TRUE WORDS
Now, as an adult with my responsibilites and obligations, I think of John Houseman's words (as quoted here) of: "You know what those executives dream about, out there, behind their desks? They dream they're great Rollerballers. They dream they're Jonathan. They have muscles. They bash in faces!" Very true.
