Keep Moving Forward
I think the trio are trying to put Potter behind them so they are not type cast, Dan has definitely said something to this effect. Helena had a well established career before HP so it isn't an issue for her.
Dan and Emma have done many different things since Harry ended I don't think either of them have to worry about being type cast but that's just my personal. I'm sure they feel differently especially about something that took up almost all their childhoods' to make.
