Pamela Anderson is in the middle of a heck of a comeback and after the Golden Globe and SAG Awards nominations, she’s becoming an Awards frontrunner in the packed lead actress category for her acclaimed performance in “The Last Showgirl.” Directed by Gia Coppola (“Palo Alto”), the drama stars Anderson as Shelley, a Las Vegas showgirl living her dream on stage until her show abruptly closes after three decades, calling into question the life she loves and sacrificed just about everything else for.
