The radio version of "The Twilight Zone," produced by Carl Amari's northwest suburban Schaumburg-based Falcon Picture Group, has been picked up for national syndication by Westwood One, the largest radio network in the country.

The show already airs on stations in 145 markets, including Tribune Co.-owned news/talk WGN-AM (720), where it's on at midnight Saturdays.

The radio series, based on the original scripts for Rod Serling's classic science-fiction drama series, features a cast of celebrity guests each week.
