Wait, the main actress wasn't Deb from Dexter?

They do look a little bit like each other but I find them very easy to tell apart.

Both are strong jawed women. That's the similarity.

With certain eyeliner Allison does look like Jennifer but for the most part they don't look all that similar. Jennifer's jawline is bigger and she's just straight up pale white. Allison looks more beige and golden haired.

I said the same thing.

Fully agree. The entire time, I thought it was Deb from Dexter. After the movie my wife told me it was actually the friend from Girls and I was in disbelief.

They do look a lot alike. I recognized her from Get Out, but they sure have similar features.

They don't look the same to me. I knew it was Alison right away since I've seen her in a couple of movies and Girls.
