1. Scarlett Johansson was pregnant during filming of this movie so many of her scenes were scheduled early in filming before she began to show. To help hide her pregnancy later in filming, three stunt doubles were hired.
2. Ultron was 8-9 feet tall, however as James Spader is 5-foot 10-inch he had to wear an antennae-like contraption made out of a thick piece of wire with two red balls. The two red balls represented the placement of Ultron's eyes and acted as a reference point for where his eyes would be.
3. On James Spader's first day on set, the cast was so impressed by his performance that they applauded and cheered for him after his first take.
4. The trailer was viewed 34 million times on YouTube in the first 24 hours after it was released. This broke the record that was previously held by Iron Man 3.
5. After this film and Avengers 3, Robert Downey Jr. was going to retire from the Marvel Cinematic Universe. However, he later signed on for Captain America: Civil War.
6. Ultron recites "No Strings On Me", a song from Pinocchio (1940), a Walt Disney film about an inanimate being who gains sentience; Ultron serves as a dark parallel of Pinocchio.
7. Captain America had the highest screen time in the movie (50:25 min), followed by Iron Man (45:34 min) , Black Widow(33:07 min) and the Hulk (28:03 min)
