We could do an entire thread on much-hyped movie and TV projects that never materialized. Remember the RED SONJA reboot with Rose McGowan? They were giving out advance posters at Comic-Con a few years ago, but the movie never happened. Or BARBARELLA with Drew Barrymore? And wasn't James Cameron talking about remaking FANTASTIC VOYAGE at one point? Or how about THE INCREDIBLE SHRINKING MAN with Eddie Murphy? That was in the works for years before Universal let go of the rights. Then MGM was circling the property, with talk of doing a serious remake, but things have been quiet on that front for some time now.
And I'm still waiting on that STAINLESS STEEL RAT movie they've been talking about forever . . . .
I’m not saying that your wrong, but this is Quentin Tarantino and Star Trek we are talking about. They are both much bigger properties than some of the names you have citied. Also, I think it’s a great sign that this film seems to have been fast tracked.
