Lao Che is a Chinese gangster in Indiana Jones and the Temple of Doom, played by Roy Chiao. The Wikipedia section on the character has the following unsourced section:
Before the death of Roy Chiao, Steven Spielberg was planning to return Che in Indiana Jones and the Kingdom of the Crystal Skull, but he declined the idea after Chiao's death in 1999. Also, Ric Young, the actor that portrayed Kao Kan, expressed interest in reprise his role of Kan in the movie, but he declined after Roy's death.
I did a quick online search, but couldn't find anything to corroborate this. Did Spielberg plan on having Roy Chiao reprise his role of Lao Che before the actor's death?
