An early casting sheet for TNG has surfaced on Gizmodo, including fun stuff like Wesley Snipes read for Geordie.

And while some are skeptical, the fact that Troi and Yar's names were switched at the last minute, and this shows Denise Crosby as the frontrunner for "Troi" when she's never said she read for the character we know as Troi lends some legitimacy to it.

I remember hearing very early on in TNG's run that Marina had read for Yar and Denise had originally auditioned to be Troi. I believe it had been mentioned at the first con I went to in Detroit in 1989, as well as in Starlog or the official Star Trek magazine or somewhere like that.
