According to Jim Carrey, he did not get along with Tommy Lee Jones, who told Carrey he hated him. Carrey later surmised that it was because at the time, Carrey's blockbuster Dumb and Dumber (1994) was released the same week as Jones's passion project Cobb (1994), financially eviscerating it and moving the film's recognition into obscurity. Carrey explained "(Jones) was a little crusty about this because 'Cobb' was his big swing for the fences," further recounting that during shooting he unintentionally visited Jones in a restaurant and cheerfully approached his table asking "Hey Tommy, how ya doing?" only for Jones to turn pale and begin visibly shaking, "...like he had been thinking of me for 24 hours... The blood just drained from his face in such a way that I realized I had become the face of his pain or something. He started shaking and he got up... like he was in mid-'kill-me' fantasy, he hugged me and said, "I hate you! I really don't like you!' And I said, 'Gee man, what's the problem?' and I pulled up a chair which probably wasn't smart, and he said, 'I cannot sanction your buffoonery!'" The very next day, they filmed the scene in which Riddler forms an alliance with Two-Face in his lair.
