There were some shots where the eyes on the mask looked a little awkward but I noticed it more when they went into the tunnel to shut down the machine so maybe it was a lighting thing because I thought it looked great when he was taking on the Deadpool army above ground.
But to the surprise of no one, Hugh was great in this between the banter with Reynolds and the more dramatic scenes he had.
I believe he's currently tied with RDJ who also has 10 appearances as Tony Stark under his belt.
Jackman: X-Men, X2, The Last Stand, X-MO: Wolverine, First Class, The Wolverine, DOFP, Apocalypse, Logan, Deadpool & Wolverine
Downey: Iron Man 1-3, The Incredible Hulk, Avengers, Age of Ultron, Civil War, Homecoming, Infinity War, Endgame
I think it's a safe bet that they'll both be appearing in Secret Wars so they'll probably be tied for a little while longer at least.
