The 81-year-old actress starred as Madame Olympe Maxime in two Harry Potter movies, The Goblet of Fire and The Deathly Hallows: Part 1. She can also be seen in Alice in Wonderland, Hugo, Trap for Cinderella, Into the Woods as the Giant, Mr. Holmes, and Enola Holmes.

What is Professor T season 4 all about?

Professor T season 4 will pick up after the tragic finale of the previous season, with Lisa's passing. Her death will be like a dark cloud hovering over the team, especially for Professor Tempest and DS Dan Winters. However, the two of them will deal with the tragedy their own way.

Season 4 will see Professor Tempest steering clear of police work and exploring a "new musical pursuit." Meanwhile, Dan will try to drown his grief in crime mystery-solving. But besides police work, as a new crime wave befalls Cambridge, Professor T season 4 will also bring some exciting new subplots for the rest of the characters, like a romantic pursuit for Adelaide.
