"This week marked 30 years since Robin Hood: Prince of Thieves has been in the world. Hard to believe three decades have passed! I've loved hearing from fans their personal memories surrounding this movie. Is it a special one to you? Tell me why," Costner, 66, tweeted Friday, along with photos from the 1991 film.
Costner -- who now stars on Yellowstone and was recently seen in the film Let Him Go -- played the titular hero in the blockbuster, which co-starred Mary Elizabeth Mastrantonio as Lady Marian, Alan Rickman as the Sheriff of Nottingham, Morgan Freeman as Azeem, Christian Slater as Will Scarlett and Sean Connery as King Richard.
The film's theme song, Bryan Adams' "(Everything I Do) I Do It For You," became a huge radio hit and won a Grammy.
