I have always loved this story and was looking forward to seeing this adaptation but afraid it was going to be Branagh'd, especially when finding out he was playing Poirot himself and cast Johnny Depp as Ratchett.

When a director wants to put their own stamp on something, they usually screw it up. Branagh dipped both of his shoes in poop (symmetrical, yes?) before stamping Christie's work. Let the story take the film where it needs to be. CGI is not where it wants to be. There's nothing wrong with a dialogue-heavy movie no matter what the studio thinks.

Casting Grade: D

* When I heard Depp was going to be in it, I assumed he'd be Poirot and Branagh as Ratchet. Depp would have been a terrible choice too but would have made more sense then Henry V himself. Depp did not fit the Ratchett part at all. Richard Widmark's portrayal in the 1974 film was dead-on. This time an Ed Harris would have been perfect. If he weren't available, Charles Dance. Dance may be too British rather than Italian/American but he still can shoot daggers with his eyes. JK Simmons would work and potentially Sean Bean or Viggo.
* Poirot - This is a tough role to cast, no doubt. Suchet IS Poirot and Finney, though exaggerated was entertaining. Branagh is not tall but this movie seems to film him as larger than his character is. He's supposed to look like a "funny-looking little Frenchman." Yes I know he's Belgian. But also little and funny-looking. All the upward angles make Branagh look bigger, not smaller. Not quite the star power and I wouldn't buy a ticket just to see Daniel Bruhl, he might work.
* Michele Pheifer as Ms. Hubbard was great. The best of the casting, so points here.
* I think Cruz and Dench were fine, as was Dafoe. Only problem here is that even as a red-blooded American male I don't remember much about Cruz's performance. That is criminal underuse. Bergman won an Oscar in this role! It's tough to live up to but still, Ken.
* Josh Gad? Fine as an actor, awful in this role. Eddie Marsan maybe? Martin Freeman? Perkins was perfect so let's go more in that direction.
* Bouc? Bouc is not and should not be 28. Yes they said he's the son of the director of the line but that's dumb. Make him a bit more of a Poirot contemporary so the chemistry is there as if they'd been friends for years.
* Ridley and Odom. This problem is more with the story "updates". Daisy's fine and Odom's acting is fine though.
* The rest of the cast is ok- meh and nothing more. The Suchet one wasn't super star-studded, but with an ensemble cast, more of the cast should have been better known.

Story itself - Here's the fun -

1. Why does the opening sequence in Syria take 20 minutes? The first question here though is "is Branagh trying to introduce Poirot to a new audience?" I would venture to guess that the vast majority of the audience knows Poirot, at least somewhat. The Syrian intro is roughly half of a chapter in the book, a quick few minutes in Suchet's version and not even really dealt with in Finney's. You can also do the egg thing on the train when he orders breakfast. That's enough.
2. Shootout? What? Why?
3. Arbuthnot. Why combine the Col and Doc characters? The 2 should be separate, either because the doc is completely removed from the subjects (book and 1974) or is a separate suspect himself (Suchet). Having them combined just seems pointless especially when you add sharpshooting to his repertoire and the inter-racial reasoning for the quiet romance with Mary. That's a lot, especially since it's 1935.
4. Moustache. Ridiculous but not in the good Poirot-image sort of way. In fact he looks more like Wyatt Earp. HP is vain and his hair would not be shown as gray - it would be dyed black and a fantastic shape, not a ridiculous rug. Again, Suchet has it beat.
5. Hanging outside. Huh? It's a snow drift in the mountains and they're outside hanging out in clothes they were wearing on the train. Winter clothes but not warm enough to have a picnic in. The Suchet version definitely got it right - the passengers were COLD. They showed that with the bundling up, the atmosphere, etc. Also, people from other coaches could be mingling. Whole point was to not let people come in or go out of the Calais coach and dining car.
6. The train tunnel ending roundup. No. Bad Kenneth, bad. Dining car, keep it there. Don't try to be clever, it didn't work nor should it. Cramped in the dining car, trapped with HP's monologue. It works.
7. Gun. Again, what's with the guns? The one under Ratchet's pillow is the only one necessary. His reasoning doesn't make sense either - Bouc is still there and he knows about the plot so they'd have to kill him too, not just HP.
8. CGI - just stop. Video trains. Not hard.
9. The Daisy note - neat trick being able to see the ENTIRE note clear as day and not just a few letters or a word or two.

Overall - 5/10 is generous. More of a 4. I really wish we could start over here but with Death on the Nile out now I hope 2 is all Branagh does. At least Nile is not one of AC's better stories. Lets wait 10 years and start again. Works for superheroes, why not one with just brains but no braun? Evil Under the Sun perhaps??
