Well, it worked out pretty much as we expected. Some of us thought Boomerang was going to run the 1966 Hanna-Barbera version of Alice in Wonderland this afternoon commencing at 1:45 PM. Here — here's what the online TV Guide listing still says…
Alice in Wonderland
1:45pm BOOM ch:297 60min
Animation and music are combined in this spoof of Lewis Carroll's classic tale. The story opens as Alice tumbles through the TV set—and into Wonderland. Voices…Alice: Janet Waldo. Cheshire Cat: Sammy Davis Jr. White Rabbit: Howard Morris. Hedda Hatter: Hedda Hopper. Queen of Hearts: Zsa Zsa Gabor. Mad Hatter: Harvey Korman.
That's the description of the '66 H-B version but what they ran instead was a 1995 animated version of Alice in Wonderland produced by Goodtimes Entertainment, primarily for the home video market.
I don't know that this is Boomerang's fault. I never saw them explicitly advertise the '66 H-B Alice. Perhaps the confusion was elsewhere.
On the other hand, the Boomerang folks are to blame for the fact that they advertised the show as starting at 1:45 and it actually began at 1:50. That means that if you were TiVoing the program before it, which was the 1974 Hanna-Barbera animated version of Cyrano (with José Ferrer voicing the title role), your recording would have clipped off the last minute or two. I don't know why they do this. I can't imagine any possible upside for the network to not give out accurate start/end times. And it's not like these are live shows and no one knows how long they'll run.
