Tom Hanks delivers anecdote at Michael Clarke Duncan memorial - video
Hanks's Green Mile co-star passed away last month at the age of 54, after suffering from respiratory failure.
The Forrest Gump actor's eulogy was a touching tribute to his friend that featured a story about Clarke Duncan trying to become a gang member while keeping his diminutive mother onside.
After Clarke Duncan's death was confirmed, Hanks was one of the first stars to pay tribute to him, describing him as "the treasure we all discovered on the set of The Green Mile".
"He was magic. He was a big love of man, and his passing leaves us stunned," Hanks said.
Also speaking at the service was fiancée and former Apprentice contestant Omarosa Manigault-Stallworth, who told mourners that the actor "worked every day" to change the perception of her as a reality star.
Other Hollywood figures to have paid tribute to the star of Sin City and Armageddon include Finder co-star Mercedes Masohn, and directors Frank Darabont and Michael Bay.
