Do you think Eric Bana could ever make a comeback?

Yes, to an extent. Quality actors like him  who can carry a project never really go away in the industry. Look at people like Jude Law and Clive Owen. Both of them were "next big thing" actors like Bana, whose tilt at A-list leading man movie stardom faded pretty fast. But they are still in demand for quality projects, particularly prestige TV (where no one has to worry about floppong box office). Owen led The Knick for awhile, while Law currently leads The Young Pope.

As a "movie star", he's never going to happen. But as a prestige leading man on TV and streaming, there will be demand for someone like him. The right project might get him some juicy character parts in movies again. The guy just needs better project selection. It's something of a weakness.

Nothing. He's still a successful working actor that's cast in semi-decent projects. But compared to his peak when he was the leading man in Steven Spielberg movies like Munich, I can see why people would consider him to have fallen off career wise. But he's not lapsed into direct to DVD B-movie hell or anything, so he can come back to prominence fairly easily. Just needs to pick his projects more wisely.

His project selection is poor/mediocre. He started to get a reputation for leading box office failures, and that sort of killed his heat as a leading man in movies, and gave him less options to pick from.

But even though things like Deliver Us From Evil and King Arthur are not memorable or good movies, they were still produced by major studios (Sony Pictures and Warner Brothers respectively). So that's the good news for Bana. Major studios still rate him enough to cast him...just not in their most prestige projects.

I'd love this. He's better than many of the so-called stars of the last years.
If we talk about actors, who would have deserved much better careers, he's near the top of my list. Nod him for Black Hawk Down, Troy and Munich and he was great in Romulus, my Father as well (still haven't seen Chopper). Would be fantastic if he got good roles again.

Sadly I doubt it will happen.

This is a good point. Bana seems to have settled down in character roles, and maybe occasional starring roles in Australian productions or smaller films. I think that's a good point to be his in his career. He can weather bombs, and maybe occasionally he'll get the big juicy part that he can sink his teeth in. It's not like he's fallen off the map hard or something.

I hope not. Terrible, terrible actor. 

Worst actor ever? You've clearly never watched Julian Sands "acting" 😂🤣 And horrible actors do not get to be directed by the likes Steven Spielberg, Ridley Scott, Curtis Hanson or Wolfgang Petersen. Just saying. 😁 That being said, you're perfectly entitled to your wrong opinion. 👍

Never say never. However, it will not be an easy task. Whether it is TV/Film, it is always possible that he can make a comeback. He definitely has the talent to play many roles. Heck, I have yet to see Ford v. Ferrari though I can clearly see him playing Bale’s role, no problem. His early success got him many offers such as xXx & Cold Mountain, in which he turned down to be close to his home/family.
