As of my knowledge cutoff in September 2021, there has been no official announcement regarding the production or release of “Iron Man 4.” At that time, Robert Downey Jr. had completed his portrayal of Tony Stark/Iron Man with the character’s storyline coming to a conclusion in the Marvel Cinematic Universe (MCU) film “Avengers: Endgame” released in 2019. However, it’s important to note that plans and announcements regarding movies can change over time, so it’s advisable to check for the latest updates or news from official sources regarding any potential future installments in the Iron Man franchise.
