The stars came out to Las Vegas to kick off "CinemaCon," one of the biggest gatherings of theater owners, studio execs and vendors.

The attending stars shared their favorite childhood memories with FOX411. "I  stood in line for the return of the Jedi on the 86th street movie theater in Manhattan," "Entourage" star Adrian Grenier shared with FOX411.

"My first movie experience, the big one for me was when I was 8 years old, in Charlotte N.C., watching Indiana Jones, it was sold out and I had to sit in the front row," Dwayne "The Rock" Johnson shared.

Christina Applegate remembers being really young and waiting forever in line for "Star Wars" with her mother and the stars from "The Man from U.N.C.L.E."

Armie Hammer and Henry Cavill both admitted it was "Titanic" that first made them fall in love with cinema. Things have changed a bit from those days with upscale food and beverages and luxury seats becoming the standard at many chains.

“You would think you would have less customers cause there's less seating but we're seeing the opposite of that," Samson Snell from Dolphin Seating told FOX411.

Cinema is evolving and wrap-around screens are being added to some theaters. Barco Digital Cinema is teaming with 20th Century Fox to bring its 3 screen panoramic movie format to 25 theaters this fall. Ted Schilowitz, the Futurist at Twentieth Century Fox says"it's a 3 screen immersive experience, surround your senses, surround your visual, we add a 3 dimensional audio with oral audio, so it's everywhere around you, it's not a single screen rectangle."

The summer movie season kicks off with "Avengers, Age of Ultron" next week and according to Rentrak’s Paul Dergarabeida 2015 is off to a record start.
