On last night's episode of 'The Inside', the third in this summer series on FOX, Tim Minear threw in a shout-out to the parent series of the show on which he previously toiled.
A movie theatre under surveillance by a potential serial killer was showing "Once More With Feeling". This was the name of the all-musical episode of 'Buffy The Vampire Slayer'.
But it's no more than an in-joke, not a connection to 'Buffy'. To have been an actual connection, we should have heard music being piped out of the theatre that would have been from the original songs performed in that episode. Perhaps the movie could then be considered a theatrical treatment of what happened when Sweet the Demon visited Sunnydale.
Instead, we heard a rendition of "Someone To Watch Over Me".
So it's a no-go on that crossover possibility.
