Superman Meets Superboy
Dean Cain, teevee’s second on-going Superman and the fourth in the cape, will be guest-starring on Smallville in the role of the murderous Dr. Curtis Knox.
Previous Smallville guest-stars included Christopher Reeve, Margot Kidder (both, of course, from the Warner Bros. movie series) and Wonder Woman‘s Lynda Carter. The former star of Lois & Clark: The New Adventures of Superman will appear in the fourth episode of the season seven, according to Variety.
