Tom Hollander is also a possibility for Leading Actor for Travesties. But I would say the current frontrunners are Garfield, Jackson, Metcalf, and Lane (if he gets put in Featured). Potter has got Play, Sets and Lighting virtually in the bag. Costume, Director, and Revival are completely up in the air right now.
There are 11 productions of a play/revival of a play that have already opened, with 8 more yet to come. None of the 11 that have already opened have set the world on fire. Except for Uma Thurman or another Leading Actress to round out the category, and possibly John Leguizamo, Mark Rylance or one of the actors in The Children, I don't think any of the acting nominees are coming from any of the shows that have already opened. And a play like Iceman could have a lot of different possible Featured Actor nominations. So there's a real lack of clarity right now.
