Today is Superman’s 80th birthday. He made his debut in Action Comics #1 on April 18, 1938. DC celebrated with the release of Action Comics #1000, and Superman himself Henry Cavill and Shazam star Zachary Levi are celebrating as well.

“Happy birthday, old man!,” Levi wrote on Instagram. “You don’t look a day past 75. Now stop running into my fist!”. He posted the photo below and tagged the DCEU’s Superman, Henry Cavill, in it as well.

This is just another example of the constant back and forth between Levi and Cavill. Superman is rumored to have a cameo in Shazam and at this point I think they’re practically confirming it for us!

Update: Cavill just posted a Superman post of his own.
