We love Winona Ryder, but her career was starting to flatline years before her shoplifting arrest — it was Angelina Jolie who won the Oscar for “Girl, Interrupted” while Winny wasn’t even nominated. Winny, pictured in a shaved head for her earlier sci-fi triumph “Alien Resurrection,” continues her descent through the bottom rungs of the C list by being cast as Spock’s mom in J.J. Abrams’s upcoming “Star Trek” reboot. Yes, the part played by the late Jane Wyatt.
