Yep, the new Superman is “super” in all ways, and studio execs are worried about it. I vaguely remember someone telling me that the guy who played Robin on the old Batman TV series had a similar problem. (Perhaps he was cast for this very attribute, which would explain why Robin is “the boy wonder”.)
And while we’re hashing up super heroes, you may want to check out a story from Jonathan Goldstein about what it was like to date Lois Lane after she broke up with Superman. Hilarious. I’ve found a link to a real audio recording of the story, but not that you’ll have to move the recording to minute 43:45 to get to the introduction before the story.
