Kirk Alyn
The first ever on-screen Superman, Kirk Alyn starred in the 1948
Superman movie and its sequel,
Atom Man Vs. Superman. Alyn may not be the hunkiest Clark Kent, but what he lacks in muscle and on-screen color, he makes up for in irresistible boyish charm. This dorky stud will always have a special place in our hearts, abs or no abs.
