The scene showing Clark Kent "crucified" in a cornfield, wearing nothing but boxer shorts, was shot on such a chilly night that Tom Welling's breath can clearly be seen in the air. A tight shooting schedule prevented any delay in the shooting. Producers called Welling "a real trooper" for filming this scene under these conditions.
When this pilot episode first aired in the US on the WB network, it ran for 70 minutes. However, a large number of fans had set their VCR timers to run for just an hour so the network was inundated with complaints from people who had missed the last 10 minutes. A shorter version now exists.
Lionel Luthor is reading a newspaper which shows a headline about "Queen Industries" which, in the D.C. Comics, is owned by Oliver Queen, a.k.a. the Green Arrow. In the sixth season, Justin Hartley joined the cast as Oliver Queen.
Lex Luthor should be 21 years old, and Clark should be 14, but the actors representing them are 29 (Michael Rosenbaum) and 24 (Tom Welling) years old, making them 8-10 years older than the characters they are playing.
