The long-awaited second instalment of the Harry Potter spin-off had its star-studded debut screening on Thursday evening at the UGC Cine Cite Bercy in Paris.
Redmayne, who posed for pictures with his wife Hannah, praised the film’s “extraordinary thriller quality” as he joined his fellow cast members up on stage just before the showing.
The lead actor, who plays Newt Scamander, teased that the new movie also has “joy and romance” bound up in it, with a hint of comedy.
Law hinted that fans of the Harry Potter franchise will be especially invested in the latest film because of the “two worlds suddenly linking”.
In a red carpet interview, the actor said: “I felt an incredible pressure to the wizarding world but it’s a wonderful character to work on. Lots of layers.
“We get to see how Dumbledore deals with his backstory. I got to go back and layer up his complexities.
“I worked a little bit on my magic only to be told that the magic was done by other people!”
Award-winning author Rowling also joined the stars on stage, addressing the excited crowd in French and explaining how her student year in Paris helped create the setting as she found the French capital “incredible and moving”.
The final trailer for the film arrived last month and gave fans their final taster of Law and Redmayne’s characters taking on Dark wizard Gellert Grindelwald, played by Johnny Depp who did not attend the premiere.
After Paris, the stars will be out in force in London on Tuesday ahead of the film’s release on Thursday November 16.
