Winston's burial in the quicksand; the music really hammers home how this WWI pilot, who is seen earlier on getting drunk, complaining about being retired, and missing his friends who died in the war, got in his plane one last time to battle a great evil and helping to save the world. His last words, before the plane crashes, are "Here I come, laddies" and laughing. He went out exactly as he had wanted.
Rick's reaction to turning a corner and finding a resurrected mummy roaring at him: scream at it, shoot it in the face with a shotgun, and run.

the entire movie is one big CMOA for Evelyn, culminating in the final scenes where she risks a second death to rescue her husband from the abyss, while her murderer, Anck-Su-Namun, cowardly flees and meets a just end.
Jonathan gets an understated one in the final approach to Am Sher, when he sheds his Cowardly Sidekick role and demonstrates some impressive marksmanship covering Rick.

Alex facing Imhotep, Anck-Su-Namun and Loc-Nah in different occasions and living as he is slowly developing from being a bratty kid to one of the bravest characters in the movie. The first occasion with Anck, he mildly snarks her when she asks him to behave. The Second Occasion he defiantly tells Imhotep that his dad is gonna kick his arse. Finally the third, he proceeds to make Loc-Nah's, a known killer's life a living hell, as he's ordered not to kill him until after they reach the Golden Pyramid.
