The actor was buried in the grounds of Los Angeles' Forest Law Cemetery, and the poignant event attracted a wide range of mourners who gathered to pay their respects -- including several Hells Angels who escorted the coffin to the graveyard.
Carradine's funeral comes almost two weeks after the actor's naked body was found hanging in a wardrobe of a Bangkok hotel on June 4.
And the late star was obviously popular in Hollywood -- more than 400 people came to say their final farewell to the Kill Bill actor.
Mourners including Michael Madsen sat around the star's resting place to share their memories of his life.
Carradine's brother Bruce explained to People.com that the day was a happy one: "There weren't a lot of tears, but there was a lot of laughter."
An investigation into the star's death is still ongoing. An initial autopsy report carried out by Thai coroners reveals Carradine died from a sudden lack of oxygen, while an independent autopsy has ruled out suicide.
