The grand photo boasts of a line-up comprising some of the biggest names in the film industry, who have worked with Hollywood's most iconic studios in the past years.
The stars include Brad Pitt, Leonardo DiCaprio George Clooney, Tom Cruise, Robert Downey Jr, Cameron Diaz, Charlize Theron, Sean Penn, and Justin Bieber.
Famous filmmakers such as Steven Spielberg, Martin Scorsese, J J Abrams and David Fincher are also featured in the picture.
"This is epic," DiCaprio said, as he entered Studio 18 on the Paramount lot and gaped at the line-up.
Photographer Art Streiber, who took the picture, said even the biggest names were humbled while clicking them for the noble cause, reported Vanity Fair.
For many celebs, who assembled and posed together on a giant stairway, it was a sentimental moment when reuniting for the photo shoot.
"It was more than thrilling... And incredibly nostalgic... to be part of that extraordinary gathering of actors who had worked for Paramount, as I had," said "Love Story" star Ali MacGraw.
Paramount Studios was founded in 1912 as the Famous Players Film Company.
