"In contrast, the control you have in a theatre is very attractive to me"

In this quote, Judi Dench is expressing her preference for the level of control she has in a theatre setting. She is comparing it to other environments where she may have less control, and specifying that the control she has in a theatre is especially interesting her. This could be translated in a couple of different methods. It might indicate that she takes pleasure in the structure and company of a theatre production, where whatever is thoroughly prepared and carried out. It could also imply that she values the imaginative flexibility and autonomy she has as a star in a theatre, compared to other mediums such as film or tv. In general, this quote highlights Dench's gratitude for the level of control she has in a theatre setting.
