65 Before I Hang ( 1940 )

This  one's  plot  is  all  very  familiar  but  at  least  it's  a  notch  or  two  above  The  Ape.

Boris  Karloff  is  once  again  a  mad  doctor ( Dr  Garth )  and  once  again  facing  execution  for  a  mercy  killing  while  exploring  a  way  to  beat  mortality. The  prison  warden  and  doctor  want  to  explore  his  ideas  further  before  offing  him. Garth  agrees  and  suggests  he  himself  be  injected  with  a  murderer's  blood. I  think  you  can  guess  where  the  story  goes  when  Garth  gets  a  last  minute  reprieve.
