Is this Crudup?

It really looks like him.  But, I could have sworn someone said it wasn't

That doesn't look like him to me. Well it does a little bit, but I do not think that it is him. Maybe it is the dude who is suffering from the backburster earlier in the trailer? I looked at the trailer again and don't know if it is him, but I can almost 100% say that it is not Crudup

I agree, I think it's the guy in the backbuster scene.

Crudup gets face hugged anyway.

Looks like Crudup to me.

Here are a few images. Tough call.

Another Crudup picture for further reference 

Benjamin Rigby

There is a bit of resemblance between the two 

The sideburns Crudup has in the Last Supper scene look very similar to the trailer.

Is Rigby in The Last Supper?

I thought I saw Rigby at the following time stamps and then got tired of following it lol.

1:27 behind the guy taking a drink

1:29

1:33 just to the right of Tennessee

1:44 taking a drink- pencil behind his ear?

I'll take a look 

Let me know what you think. This still does not answer the OP however.

Possibly,actually likely,but yeah it doesn't actually give us any answers.

Centauri is right, its Rigby. Crudup's ears are slightly larger and he has a sterner profile. 

I have to say, Billy Crudup was so awesome in Watchman!!!

@Facehuggers  Yeah he is great in Watchmen, great flick!

And I can't believe that what's his name was wrong. Unbelievable

It's not Crudup based off facial structure.

However, it would be kind of neat to see someone get facehugged after a good ear-sporing..

Can you all picture the resultant Neomorph and Xenomorph creatures fighting it out within the individual as they gestate...?

It would probably make for a good "The Mask"(movie) type scene. 

Rest of the crew wouldn't be sure if he was infected, been possessed, or tripping off acid...

Its not Crudup but Benjamin Ridby. You can see on the full cast and crew picture. He is in the right back corner next to Danny Mcbride with white long t-shirt, while Crudup is in the front right next to Michael Fassbender
