I just watched Charlie's Angels (2000 original movie with Cameron Diaz, Lucy Lieu and Drew Barrymore) in Dolby Atmos with its 4K/Atmos retrofit. Charlie's Angels had pretty decent Atmos sound with a lot of overhead effects (including a great helicopter set near the end putting things all around above and flying across the ceiling at different points depending on the camera angle) and plenty of ear level surround use as well including the rear surrounds. It's not the best Atmos track I've ever heard, but it's at least very competent, IMO. I wasn't disappointed like I was with the Back to the Future trilogy (i.e. I just watched half of Part III and it was poor surround in general like the 1st movie let alone overhead effects which were nearly non-existent up until that point save the clock tower recount at the start). Charlie's Angels is pure cheese (or should I say cheesecake given how great the ladies look?), but it's still fun to watch 20 years later and Atmos brings the sound up-to-date on this one. I haven't seen any signs of an updated 4K/Atmos retrofit of the sequel that added Demi Moore to the mix, but I hope it gets an update also soon as well.
