Entertainment news today spans grief, legal drama and festival momentum. In New York, prosecutors in the Luigi Mangione murder case scored an important pretrial win after a judge allowed jurors to see a gun and notebook recovered from his backpack, though some other seized items were reportedly excluded, setting up a sharper fight over how damaging that evidence may be. At Cannes, A24 landed one of the market’s hottest deals, snapping up global rights to Jordan Firstman’s well-received “Club Kid” after a bidding battle that underscores the indie studio’s continued appetite for buzzy auteur fare. The industry is also mourning Tom Kane, the prolific voice actor behind Yoda in “Star Wars” animation and Professor Utonium in “The Powerpuff Girls,” who has died at 64. Elsewhere, authorities in Spain are investigating the death of a British tourist after a reported fall at Mount Urgull.
