Ridley was honoured with the 2,564th plaque on the Walk of Fame in Los Angeles, and he was joined at the event by his Gladiator star Russell Crowe, Salma Hayek, The Martian actress Kristen Wiig, producer Jerry Bruckheimer, actor Djimon Hounsou and director Eli Roth.

During his speech, Russell remembered the times he has worked with the director, and honoured his achievements in Hollywood.

"We fought back the barbarian hordes deep in a forest... right next to (Britain's) Gatwick Airport," he laughed. "We harvested grapes in the south of France together, we held a medieval castle to siege - we've done a lot of things...

"You're talking about a guy like Ridley. When you mention his name - the birth scene in Alien, the streetscapes of Blade Runner, Geena Davis and Susan Sarandon going over a cliff in a car - the images he's created, the adventures he's taken the audience on, have just been amazing... This honour, well, quite frankly, it's just about time, isn't it?"

"We are all here to celebrate and honour your incredible body," Kristen joked. "And of course we have to mention your museum of Believe It or Not, right down the street."

When Ridley took to the podium, he remembered his late brother Tony and dedicated the star to him, adding, "He was my buddy and my partner. I know that he's watching."

Top Gun director Tony Scott took his own life in 2012 by jumping from a bridge in California.
