IT’S THE ONE THAT YOU WANT!

It’s been 40 years since the John Travolta/Olivia Newton-John musical “Grease” hit movie theater screens, and in honor of the milestone, the film is being released in theaters April 8, 14 and 11, as part of the “TCM Big Screen Classics” series. The movie’s soundtrack spawned a multitude of hits including the title tune, “Hopelessly Devoted to You,” “You’re the One That I Want” and “Summer Nights.” More than 700 theaters across the country will be participating in the celebration.

WHAT’S UP, DOC?

At the DOC10 festival, viewers don’t just watch promising new documentaries, they discuss them with the directors and other key figures. This year’s edition, continuing through April 8 at the Davis Theater, 4614 N. Lincoln, includes the Ruth Bader Ginsburg profile “RBG” (9 p.m. April 7) and recent Sundance winners “On Her Shoulders” (4 p.m. April 7) and “Crime + Punishment” (9 p.m. April 6). Closing out the fest at 7:45 p.m Sunday will be “The King,” about which the Sun-Times’ Richard Roeper writes, “I can’t think of a less-inspired documentary subject than Elvis Presley — which makes it all the more impressive that Eugene Jarecki’s ‘The King’ challenges us to look at the life and legacy of Elvis in ways I never imagined.” For the full festival schedule, visit www.doc10.org.
