Mark Ruffalo’s latest tweet on Robert Downey Jr’s birthday received immense love from the fans. They praised the actors and mentioned how much they miss Hulk and Iron Man duo. Check out a few replies to Ruffalo’s tweet wishing RDJ a happy birthday.

Mark Ruffalo and Robert Downey Jr as Hulk and Iron Man appeared in four Marvel movies together - The Avengers, Avengers: Age of Ultron, Avengers: Endgame, and an uncredited cameo in Iron Man 3. They were also part of Avengers: Infinity War but did not share the same screen. The science bros have together invented a few things in the MCU, including the time travel suit.

Now only Bruce Banner remains in the MCU as RDJ’s Iron Man sacrificed himself in Endgame. The two actors have also worked together on David Fincher’s 2007 released historical mystery thriller film Zodiac with Jake Gyllenhaal and others. Besides their reel life, they have been good friends in real life, too.
