Generally speaking, it's not seemly to say if you turned down a Hollywood role, out of respect for the person who took it.
This doesn't stop other people doing it, of course.
Reports are now coming in detailing who was considered and who turned down the roles of Christian Grey and Anastasia Steele in the forthcoming 'Fifty Shades of Grey' movie adaptation.
According to the Hollywood Reporter, first up to pass was, reportedly, Ryan Gosling, who was 'not interested' in the role.
This would more likely mean he turned down an offer to audition rather than the role itself, though the 27-year-old was said to be the 'original prototype'.
'Tron: Legacy' and 'On The Road' star Garrett Hedlund was also said to be in the frame, but 'couldn't connect with the character' of Grey, as was British actor Christian Cooke.
All this doesn't tally much with writer EL James's choice for the lead, which, according to Bret Easton Ellis, was Robert Pattinson.
Meanwhile, British actress Felicity Jones was, at 30, eventually deemed too old for the role of Anastasia Steele, while Shailene Woodley was up for it but had to pass due to obligations to her forthcoming movie 'Divergent'.
Also in the frame were Alicia Vikander, Imogen Poots and Elizabeth Olson, but Dakota Johnson, who snared the role in the end, was ultimately director Sam Taylor-Johnson's top choice.
The fans of the book, however, have a different opinion.
A petition posted on Change.org demanding 'Magic Mike' star Matt Bomer and Alexis Bledel are given the roles, has over 41,000 signatures so far, around 9,000 short of its 50,000 target.
The producers are, of course, hardly obliged to do anything about it.
Dakota Johnson is best known for her small role in 'The Social Network', where she introduces Napster founder Sean Parker (played by Justin Timberlake) to Facebook. Watch the slightly racy scene below.
