Ed Asner made his second appearance as art thief August March last week on the new version of 'Hawaii Five-O'. It was his third appearance overall, however he played March the first time on the original series over thirty years ago.
So he was two different men named August March, each in a separate TV dimension. Had he played the role in a third TV series, Asner's character might have been eligible to be inducted into the TV Crossover Hall of Fame.
But that's not going to happen now. In this recent episode, August March deliberately stepped backward into the street and was mowed down by a huge truck.
Because that alternate August March was interacting with counterparts to McGarrett and Dann-O, his life was already different from that of the August March from Earth Prime-Time. So that original televersion probably had a different destiny.
There's no real option for that August March to show up again in Toobworld. ('NCIS: Los Angeles' might have been a candidate, but that would mean a lot of splainin for me since that show already crossed over with the new 'Hawaii Five-O'. 'CSI' might work.....) So I like to think it wouldn't have been possible anyway.
I think the original August March should be considered dead in Earth Prime-Time as well. But not hit by a truck - he probably died in prison.
