To Fiercely Red:

I assumed that the "25 year celebration" was just an excuse to put CTC on Oprah. That was the best they could come up with. If they went back to Endless Love, the number of years wouldn't be even. Besides, Endless Love tanked at the box office. Plus, if they put any emphasis on that film, they would have to talk about Brooke Shields again. Tom had only a small part and maybe his ego wouldn't be able to handle the fact that Brooke was the star of that film and he was little more than an extra.

So it was probably 25 years of HIM being the center of attention in every film.
