Ken Rudolph’s review published on Letterboxd :
Surprisingly for a Zemeckis film, this was a resolutely retro WWII romantic drama. Unsurprisingly it opens up in Casablanca in 1942. Comparisons with another famous film are inevitable. However, this spy and resistance film is in color with gorgeous costumes and steamy sex scenes. And yes, Brad Pitt is hot; and there is evident chemistry on screen between him and Marion Cotillard. It's a potboiler, sure; but reasonably entertaining. However, Casablanca it is not.
