The surviving members of The Doors claim that Val Kilmer did such a good job playing and singing as Jim Morrison that they could not distinguish his voice from the real Jim Morrison. In a 1991 interview, Robby Krieger said that Kilmer did a good job portraying Morrison and that "it was scary sometimes how much he was like Jim". John Densmore said in a 2015 interview to Forbes that Kilmer should have been nominated for an Oscar for his performance as Morrison, and that Kilmer was so close to Morrison that it gave him the creeps on the set. After Kilmer's death in April 2025, the band issued a statement crediting Kilmer's performance as Morrison for helping introduce the band's story and music to a new generation.
Robby Krieger, the guitarist in The Doors, insisted that the scene showing the band rehearsing "Light My Fire" makes this clear that he, not Jim Morrison, composed the song.
Jim Morrison's real grave is shown at the movie's ending, filmed at the Père Lachaise Cemetery in Paris, France. The headstone has since been changed, and the graffiti was removed from the surrounding graves at the request of Jim's parents. The bust of Jim was stolen sometime in 1988. The grave is also surrounded with a steel fence to prevent further vandalism to the tomb, as pieces of the stone had been chipped off and stolen over the years. The bust was eventually found and returned in 2025.
Val Kilmer broke his arm badly when he performed a jump from the stage into the crowd. The stuntman failed to catch him, leaving Kilmer with an abnormal growth on his right elbow. The growth is clearly visible in Fuego contra fuego (1995), when McCauley discovers Shiherlis sleeping in his living room and begins briefing him on their itinerary.
