Hoping to beat the heat this Labor Day weekend? The Red Lion Hotel and Alex Theatre in Glendale host Hollywood’s oldest classic film fest, Cinecon, where more than 30 new prints of little-seen features and shorts unspool Thursday-Monday.

The 35th annual Cinecon features an appearance by Howard Keel, who will speak at the Sunday screening of his starrer “Annie Get Your Gun” (1950), which will be the first theater showing of the pic in more than 20 years.

Gloria Stewart of “Titanic” will also make an appearance, signing copies of her autobiography “I Just Kept Hoping.”

A panel of Disney vets — including actress Glynis Johns (“Mary Poppins”), Academy Award-winning songwriter for “Mary Poppins” Robert B. Sherman and “Fantasia” animator Bill Justice — will discuss the studio’s latest bio, “Walt: Favorite Memories of Walt Disney.”

“We’ve got an amazing group of people that trace the complete history of Hollywood,” said fest organizer Robert Nudelman.

Other films to be featured include the Douglas Fairbanks starrer “In Again-Out Again” (1917), “The Mystic” (1925) helmed by Tod Browning, “Loves of Carmen” (1927) with Delores Del Rio, the Harry Langdon starrer “The Chaser” (1928) and “The Woman I Stole” (1933) with Fay Wray.

Closing the fest will be Cinecon’s career achievement awards banquet, honoring this year’s celebrity guests.
