He enlisted in the army in honor of his late wife, Carole Lombard. She had been killed in a plane crash while on tour selling war bonds.
He gave his 1934 Oscar to a child who admired it, telling him it was the winning of the statue that had mattered, not owning it. The child returned the Oscar to the star’s family after his death.
