Martin Sheen Was ‘Not Too Keen’ on Son Charlie Airing Out ‘a Private Family Matter’ in Netflix Doc

Martin Sheen refused to be involved in the Netflix docuseries about son Charlie’s hard-partying life and journey to sobriety because he’s still bitter about what the recovering addict put his loved ones through, sources say.

According to an insider, the Major League star, 60, is exposing his sordid past in the film, titled aka Charlie Sheen, because “he’s desperate for closure.”

Yet, insiders say Apocalypse Now legend Martin, 85, shied away from the two-part documentary, which he feared would be littered with folks singing Charlie’s praises — despite his past self-destructive behavior.

Charlie is seven years sober, but the onetime Hollywood bad boy long battled booze and drug addictions — and reportedly dropped more than $1.6 million on prostitutes.

Charlie was once the highest-paid actor on TV — pulling down $1.8 million per episode of Two and a Half Men — but was fired from the CBS hit in 2011 after three failed rehab trips in 12 months. He also had multiple manic meltdowns, including one interview in which he claimed to have “tiger blood.”

An insider says, “Charlie feels terrible over what he put his father through. He has so much guilt, and he still gets teary thinking about it.”

The docuseries includes many people close to the reformed troublemaker — including ex-wives Denise Richards and Brooke Mueller, his Two and a Half Men costar Jon Cryer and series cocreator Chuck Lorre.

The insider says, “Martin’s not too keen on Charlie laying it all out in vivid detail about his past addiction to drugs and prostitutes. He loves his son dearly but disagrees with him. To Martin, this is a private family matter.”

In the documentary, the remorseful Charlie says, “I can’t imagine being my dad. I really hurt the people I love.”

However, the insider points out that Martin is “an old school guy” and “doesn’t like dirty laundry aired in public!”
