Lea Michele would be "nightmare", not dream casting for "Funny Girl". Wouldn't you rather have someone who can act and sing? Michele has proven on "Glee" and especially the Tonys that she can do neither. Adam Lambert would be more believable as Fanny Brice than Lea Michele; at least he sings better.
Seriously though, I think Matthew Morrison would be great as Nicky Arnstein and I would cast Tammy Blanchard, a superb singer and actress, as Fanny Brice, although at 33 she might be considered too old for the role.
