I agree. Cladwell is really a supporting role, but I suspect Cullum got the nomination (over Foster) because he was better-known.
Cullum also was a two-time Tony winner, for Leading roles in ''Shenandoah'' and ''On the Twentieth Century.''
As for ''Jerome Robbins' Broadway,'' it's interesting to revisit the billing. Everyone is listed below the title, but right underneath the teeny word ''Starring'' are Jason Alexander and Robert La Fosse's names. Then there's a block of 10 other names, followed by: and Charlotte d'Amboise.
I'm assuming the Tony nominators used the positioning of the performers' names in the billing to decide who was Leading.
The 1989 Tonys seemed intent to fill out Actor and Actress in a Musical - unlike the 1985 season where they ditched those categories.
