Even after a major blockbuster is finished shooting, studios are usually strict about keeping props, costumes and other production items under lock and key. However, sometimes they're lenient about letting actors leave with one or two things, especially if it's one of the main stars. In Ben Affleck's case, he hit the jackpot after Batman v Superman: Dawn of Justice, because he was able to go home with one of the Batsuits.
I did ask to keep the suit, and they let me keep it, sort of. Not the one that I actually wore but a replica of it. I still have, but I still have it on a dummy at my house. I don't know why. Like, I just have the Batman suit there.
Okay, so it's not the Batsuit Ben Affleck was wearing for Batman v Superman scenes like that warehouse brawl, but being able keep one of the replicas is still quite cool. However, contrary to what superhero stories would have you believe, putting on such an elaborate costume takes a lot of time, so Affleck probably hasn't tried donning Bruce Wayne's battle gear. Well, maybe he tried once, decided it wasn't worth the effort again and has kept it on the dummy since then.
Even so, simply having a Batsuit on display in your home ranks high in bragging rights. Maybe Ben Affleck looks at the costume when he needs extra inspiration for working on the Batman movie, almost recreating the Batman v Superman moment below. Now all he needs is that defaced Robin costume, and he'll be set. The interviewer also suggested that Affleck move the Batsuit to the sitting room and decorate it for Christmas. Why not? Light-strung Batsuit trumps a Christmas tree every time.
Along with his Batsuit, Ben Affleck also revealed that he was able to keep a Batarang, Batman's primary projectile weapon. To be fair, that's significantly easier to bring back, but a good parting gift nonetheless. Of course, in the DC Comics world, Batarangs are a dime a dozen for Bruce Wayne. He's even letting Barry Allen, a.k.a. The Flash, keep one in Justice League. The only way to top any of this is if Warner Bros was gracious enough to let Affleck keep the Batmobile, and that's extremely unlikely to happen. If Affleck wants the Caped Crusader's ride, he'll have to commission it from another source.
You can see Ben Affleck reprise Batman when Justice League hits theaters later this year on November 17.
