Nielsen was the star of a TV series called "Police Squad> which were the basis for the Naked Gun movies. Police squad was cancelled like 4 shows into the season for the following reason:
ABC entertainment president Tony Thomopoulos said "Police Squad! was cancelled because the viewer had to watch it in order to appreciate it." What Thomopoulos meant was that the viewer had to actually pay close attention to the show in order to get much of the humor, while most other TV shows did not demand as much effort from the viewer. In its annual "Cheers and Jeers" issue, TV Guide magazine called the explanation for the cancellation "the most stupid reason a network ever gave for ending a series."
Before the naked Gun movies were made, Nielsen ent to UK to make some commercials for some drink with a name like Red Rock Cider
"Red Rock Cider is not red , nor are there any rocks in it"
Apparently these commercials were quite successful but weve never seen them here in the US or could I find them in any product list. Ill keep looking (Mybe Ill send A PM to Butterflynet , she is a whiz a digging up obscure web stuff)
