4 essentials: Chiraq, Janis, Tom and Sam

The Four Essentials for December 2, 2015

1) “Chi-raq,” Spike Lee’s new film
2) “Janis Joplin: Little Girl Blue,” a documentary about the music and the life of the great singer
3) “Going Clear,” a chilling documentary about Scientology from Alex Gibney and Lawrence Wright available on HBO.
4) Looking at the films of Sam Mendes, director of the last two Bond Films.

And bonus, an old Christmas film that should be better known. Fred Macmurray and Barbara Stanwyck star in in “Remember the Night.”
