Dean Cain wrote this episode and based Mr. Schott off of the Toy Man. He also has his mother in a small part and a new girl at the Daily Planet who didn't cut it as a regular.
Superman flies across the moon, pulling a sledge carrying Lois, Jimmy and Parry (who is in a Santa/Elvis suit). Dean Cain got this from E.T. and the stories involving Santa and Rudolph.
Dean Cain originally wanted Clark to have dinner with his family in Smallvile, then zoom over to Metropolis and have another with Lois, but Smallvile was cut out.
