Has HHH life and career been interesting enough to justify a bio pic ?? We're talking about a full length motion picture here. Really, since the National Expansion and initial boom in popularity with wrestling in pop culture there are the wrestlers who have the name recognition, who made significant, game changing contributions, and whose lives outside the ring have been colorful enough to warrant such a film...Hogan, Flair, & Austin. Remember, if we're really talking about if someone is "worthy" then it starts with those three, three legendary, larger than life, highly successful, influential, game changing stars who defined the most successful eras in the industry.
After that no one really is in that league. You can make a strong argument in terms of star power and interesting back story for Savage & Dusty Rhodes, maybe Andre The Giant. From there it tales off considerably when discussing wrestling stars that a mass movie audience would have any interest in seeing. I would put Vince McMahon himself in this category.
There are some lesser stars who have extremely compelling back stories...HBK dealing with status as arguably the most hated figure behind the scenes and his reckless drug and alcohol abuse (leading into his going to re hab, getting married, etc), SuperStar Billy Graham, Tully Blanchard and a few others.
Fact is I know HHH isn't in the Hogan/Flair/Austin category of cross generational, cross eras, superstars and quite frankly I doubt he has some of the more compelling behind the scenes history that those three have to make his story compelling enough for a full length movie. Im not sure I see HHH with Savage, Dusty, Andre either though he's close, but again they also have compelling outside the ring histories that I don't see with HHH.
Honesty, while I wouldn't mind seeing an independent hour long documentary on him like what A&E did for Hogan in the late 90s I just don't see HHH as a biopic worthy figure.
