For the past two weeks during the credits for Let's Dance for Sport Relief there has been a "WITH THANKS TO Saturday Night Fever Courtesy of Paramount Pictures" credit. Despite watching both episodes, I don't recall them using a clip from Saturday Night Fever on either.
Fatima Whitbread and The Cuban Brothers danced to You Should Be Dancing by The Bee Gees which was used in Saturday Night Fever, but would that require such a credit? Both programmes also featured a song from the Bugsy Malone soundtrack but this was not credited in the same way.
The acknowledgment could refer to the use of the song, not a clip from the motion picture.
Bugsy the musical is published by Weinburger (I think) and probably falls under a more generic rights condition not requiring a producer acknowledgement.
Rita Simons: My Daughter, Deafness and Me is being shown
3 times
on BBC One over the next day or so: tomorrow morning at 00:35 (signed), tomorrow evening at 22:40, and Wednesday morning at 01:20 (signed).
It seems particularly unusual that they are showing it signed twice, with the repeat of the signed version being shown less than a couple of hours (or less in some of the nations - just 50 minutes in Scotland) after the unsigned version finishes.
