>Looking for  American films dealing with capital >punishment from 1900-2000.

In no particular order, limited to no particular
application, and off the top of my head:

Return to Paradise
Angels with Dirty Faces
Dead Man Walking
Last Dance
The Green Mile
The Execution of Private Slovak
They Died with Their Boots On (?)
I Want to Live
The Oxbow Incident
Mata Hari
Apocalypse Now
The Commancheros
Hang 'em High
Judge Roy Bean (?)

And others, no doubt . . .
