There's something(s) way off about the poster for 'The Invasion'. The font, for instance -- too clean, looks like a good choice for a musical set in the near future. The digital 'melt' effect of the bad guys at top of poster is too photo-shopped looking, also too clean. The placement of the two stars is very retro, like what you would have seen in the 50s. Their faces take up too much space (I didn't want to say 'their heads are too big'). Craig's head should be lowered so there's less vertical space taken up.
Taglines, clunky -- also seem like they're from the 50s when an audience would have had to have been told what to expect from a new genre.
'Do not trust anyone'. -- we already knew that. Being unable to trust anyone is de rigueur for paranoid thrillers.
'Do not show emotion'. -- well, duh. You don't joke with zombies or people whose minds have otherwise been commandeered. As for laughing or crying, please. We know we have to be stonefaced around the living-impaired.
'Do not fall asleep'. -- okay, that's pretty good. The 'avoid REM sleep' thing is alright. That should probably stay.
Okay, on to layout. The title at the bottom doesn't work here. Should be moved to the traditional placement below the names of the stars at the top of poster. Should also be shifted off-center, probably to the left, to work with the arrangement. Also, put it all on one line. Stacking the 'the' on top doesn't work -- there's plenty lateral space, not much vertical space. (On second thought, title should stay in the center -- composition should be changed so it will look good in center).
Okay, from the look on her face I don't think she's too happy with my suggestions, but I have just a couple more.
The color scheme is too simple, too flat -- there's just too much red. Try adding some depth and layers, use some dark purples with very grayed-down green around the edges (something that says 'My soul no longer exists').
Daniel's head is floating in space -- give some definition to his shoulders. (And, what's with Craig's expression? Not very paranoid, heroic, or 'you can't trust me even though you think you can'. What does that expression say? 'Look, I think there's a parking spot half a block up on the right.')
Where's the 'mother protects her child' element seen in the trailer? This poster makes the movie look like it's all about the relationship between Craig and Kidman, when the trailer hardly shows this at all. Trailer emphasizes the relationship between Kidman and her son. Come on, guys. This is Movie Poster 101 stuff.
Net effect: looks like someone slapped this together on a laptop in their spare time. Please apply above fixes.
