CBS made numerous 'disclaimers' during the broadcast, which is why no one ever successfully sued the network or Welles, despite numerous lawsuits.
The telefilm was produced by Paramount Television. The book "War of the Worlds" was adapted into motion pictures by Paramount Pictures in both 1953 and 2005.
As he prepares to abandon his family at the start of the movie, Hank Muldoon complains that he's 28 but looks like he's 40. Vic Morrow, the actor playing Muldoon, was 44 when the movie was filmed.
Apparently to save on royalties, the Paramount-owned "Cocktails for Two" is substituted for "Stardust" as "the tune that never loses favor" in the mock hotel orchestra broadcast.
A few scenes from the 1953 War of the Worlds were inserted in this film including the scenes where people are huddled in a country store, in a factory and people leaving a building. That scene has both Gene Barry and Ann Robinson and they can be seen (all though only their backs) as they approach a police car.
