Two understudies I've seen have stuck with me for years... Janine LaManna - who went on for Chita in Spider Woman during its Chicago tour run, when Chita broke her leg(?), was fantastic. Didn't realize "no Chita" until the curtain rose... and she definitely won audience over (Carole Lawrence was soon brought in to finish run).
And Barbara Marineau was on for (the terrific) Betsy Joslyn in the Cincinnati run of the Into the Wood tour one night - and thought she was perhaps the best of the 6-7 Witches I saw (including Bernadette, Phylicia, Dussault, Cleo, Joslyn, etc...)
Finally, more recently, I was as stunned by Aaron Walpole's super Valjean, in the Toronto run of Les MIS, as by the trick the production pulled by printing an entirely new cast insert for that day's performance, which listed Valjean as Walpole, without noting he was either Ramin 's understudy, nor that Ramin wasn't there. Even the cast board in the lobby noted Ramin would be on at that performance - as that's the first thing I checked - and there was no announcement, etc... Only noticed the Walpole trick seconds before the show started - and was a bit angry at the deceit - but Walpole was so good - buy any measure - that it was hard not to love him. (this was not a scheduled/announced Raman Thursday off, day off, etc... it seemingly was a missed Sat night they tried to hide as he was there all surrounding performances.
