UPDATED: Old Dorsal Spikes? New images from Godzilla 2: King of the Monsters featured in Empire Magazine

Hmm.. Interesting..

 It could be a flash back scene 

Honestly, its' hard to tell for sure from that angle. 

I'm sorry if this turns out to be a spoiler, but I think Godzilla will get a power boost at some point in the movie, which will cause his dorsal spikes to transform into this "classic" style.

In the latest TV spot, during the intimidation scene, his spikes seem to bear a closer resemblance to their 2014 design. It's a bit hard to tell though, they're being obscured by the water.

Yeah, sorry. I can't tell. It's hard to know from the angle, but we won't fully know unless that shot is shown in motion.

Has anyone else noticed how they are keeping Charles Dance's character secret ? He's got to be Conrad as an old man. Every actor has a character name but his... www.imdb.com/title/tt3741700/fullcredits

I find that rather interesting. He may be the one who gets Kong and Godzilla to fight each other... or bring them together to fight something bigger and badder than both of them. I would find it hard to believe that Conrad would be a villain in this movie... but if he is... I like to know what turn him that way. Just speculating here.

Just speculating, but IF Charles Dance's character IS James Conrad, then MAYBE he wants Godzilla dead and Kong to be king. Real unlikely, but just speculating
