Big name celebrities.

I'd like the show to have A-list celebrities guest star on it. I'm talking about people like Dwayne Johnson, Tom Hanks, Will Smith, or Leonardo DiCaprio. Why hasn't this happened yet?

Budget I suppose. However, if I recall, the budget increased for this final season, so maybe we’ll get an A lister or two. Maybe someone from the pony movie . Robert Downey Jr made some pony jokes before, so maybe they’re considering casting him as well

If Discord ever had a brother, I think the perfect person to play the role would be Kelsey Grammer 

Robert Englund would be a great choice to play someone who's an antagonist to Luna

They don't need to shell out the big bucks to get a name actor when they already have a sturdy base of fans and don't need to use special means of attracting new ones. It would be cool though. I'd love to see (hear) some big names getting into the act with the ponies. That would be a lot of fun.
