Yuri Rasovsky brought radio plays back to the future, or at least to the 21st century. The
first play, broadcast on 4 Apr 2000, was based on Heinlein’s time travel story, “By His
Bootstraps,” with the role of Bob Wilson distinctively voiced by Richard Dreyfuss. I'm not
certain, but host Harlan Ellison might be the voice of the narrator in that
episode.
At least two later time-travel stories were also produced.
