With Avengers: Endgame packed with all sorts of familiar faces from the Marvel Cinematic Universe, an updated IMBD listing for the film has actor Ty Simpkins listed as reprising his Iron Man 3 role as Harley Keener.
The actor's filmography on the Internet Movie Database has been updated to include Avengers: Endgame with Simpkins' previous role credited.
This corroborates a report from last year that mentioned Simpkins had been cast in the film to return as Harley Keener.
The 2013 Iron Man sequel introduced Simpkins' Harley as a young boy living with his single mother in Tennessee that helps Tony Stark recover after his Malibu home is destroyed by the Mandarin. Before departing to stop the Mandarin once and for all, Stark helps Harley deal with a local bully and gifts him his own tech-infused workshop.
Avengers: Endgame will arrive on April 26, 2019. Directed by Joe and Anthony Russo, the film stars Robert Downey Jr., Josh Brolin, Mark Ruffalo, Tom Hiddleston, Chris Evans, Chris Hemsworth, Jeremy Renner, Chris Pratt, Elizabeth Olsen, Chadwick Boseman, Sebastian Stan, Benedict Cumberbatch, Paul Bettany, Samuel L. Jackson, Cobie Smulders, Benedict Wong, Zoe Saldana, Karen Gillan, Vin Diesel, Dave Bautista, Pom Klementieff, Scarlett Johansson, Tom Holland and Anthony Mackie.
