I'm sorry but it's my favorite Michael Caine movie. Yes, yes there's a plethora of amazing movies, but this one is the one I fell in love with as a child and it's stuck with me now. He's stellar in it too.
No, they found the original reels for the missing track, so it has been remastered to 4k widescreen. The whole alternate version with the song is in the special features on Disney Plus
I've seen this film every year since it was on vhs. Last night I took my kids to see it at the cinema and it still holds up. "When Love is Gone" was back in it's rightful place and having not seen it for a good few years it's such a welcome return. The pacing is totally messed up by it's removal.
