Is Ben Affleck's Back Tattoo a Tribute to Harry Potter?

Remember back in July when those photos of Ben Affleck with a lower back tattoo hit the Internet? Well, we're getting another, more in-depth look at Ben's ink — and it's pretty impressive. The actor, who is currently filming the '20s-era flick Live by Night in LA, was photographed on set in a backless hospital gown that showed off the huge, colorful phoenix tattoo on his back. Being that the phoenix is a symbol of rebirth that literally rises from its own ashes, it could be that Ben got the massive piece as a metaphor for his life and career, as a way of dealing with his split from wife Jennifer Garner earlier this year, or, as one POPSUGAR editor mused, "Maybe he's a big Dumbledore fan."

The photos of Ben's large tattoo come not long after rumors started swirling that he and his Live by Night costar Sienna Miller may be more than just work buddies; the two were spotted holding hands between takes on Monday.
