Jurassic Park director Steven Spielberg said: ''Dickie Attenborough was passionate about everything in his life - family, friends, country and career.
''He made a gift to the world with his emotional epic Gandhi and he was the perfect ringmaster to bring the dinosaurs back to life as John Hammond in Jurassic Park."
Star of Gandhi Sir Ben Kingsley said he had grown to love the director, who had worked tirelessly to bring the Indian leader's story to the big screen.
''He placed in me an absolute trust and in turn I placed an absolute trust in him and grew to love him,'' said Sir Ben.
''I along with millions of others whom he touched through his life and work will miss him dearly.''
