The Arrowverse crossover Superman at the end is Tyler Hoechlin. The Lex Luthor opposite him in that crossover era is Jon Cryer.

Quick scoop

  • Superman: Tyler Hoechlin
  • Lex Luthor: Jon Cryer

Small clarification

If you meant the later Superman & Lois version with Lex Luthor, that Lex is Michael Cudlitz , not Jon Cryer.
