Isla's dress was much prettier though!

I see it...

I think they are both beautiful ladies! But, I LOVE Isla's dress!

I think Isla's was better on camera - both gorgeous though.

My husband already has a tough time telling these two apart, he thinks of them as one red headed funny actress...

That's hilarous that you've written this, because my sister literally cannot tell them apart. She has no idea which is which, no matter how much I tell her.

GAWD, I CANNOT STAND AMY ADAMS!!!!

Wow. Those looks are incredibly similar! It does work well for the two of them though.

That's what I thought of when I saw Amy! Although I think Amy did a much better job

I've ALWAYS thought they look so much alike...I used to think they were the same person!

I like them both a lot, but I REALLY love Amy.

I think of them as pretty similar overall, but they definitely look a lot alike here. It doesn't surprise me tho that they both choose that look. I have a friend who is a red head and she loves the colour green. It just looks so amazing on red heads. and the cut works well on both of them because of how they style their hair and their body types.

They look SOOO ALIKE I get them confused!

I thought for the longest time that it was Isla in Enchanted, not Amy....they are interchangeable for me!

Isla just pops out at you! My eyes naturally went directly to her. The other redhead looks like a duller, less sparkly version.

Ema! I also thought they were the same person, some time ago!

Prefer the less shiny dress of the two. It looks more dignified.

I see it too....Isla's dress was MUCH prettier though. Amy's dress just didn't do it for me.

OMG total flashback!!!! i think they both look gorg but i like isla's a tad bit better...

Total resemblance! Isla looks so much prettier, her dress and hair are so much sexier. I also thought that Amy's useless golden purse was the dumbest accessory of the night.

amy adams is beautiful much more than isla

i see it, but i think they're both gorgeous redheads, the green flatters both of them so well.

omg i thought the same thing!!!! although isla is my fave!!! she's soo beautiful!!

I'm so confused! I thought they were the same person. Thank goodness that's all cleared up!

This was all I could think about when I saw Amy Adams. And no, my husband can't tell them apart either.

I had the same problem with Anne Hathaway's dress. It was so similar to the one that Kate Winslet wore to the Oscars in 2002 that I couldn't get past it, even though Anne looked gorgeous.

So here is my confession: Up until the oscars I thought Isla fisher was the one in enchanted and I never new who amy adams was. I was so confused Sunday night.

Isla Fisher is so much prettier sexier and more confident than Amy Adams.

i can totally see the resemblence!

I've always had a hard time telling them apart. Isla's dress photgraphs much better though....

Yes, but Isla looked prettier, her dress and hair just looked better.
Amy's dress looked a tad too dark and her hair was a tad too long.
Her hair is at the point where it makes her face look long.

Just cause I can never remeber is Amy the one who play the blond in Mean Girls?

I can see it a little.

luv isla, shes adorable...amy is annoying, but they do look similar.

I don't know, I can see the resemblance, but Amy is much prettier and looked very classy, while Isla looked a bit... well, a bit slutty TBH. The dress was fab, though.

I don't really think they look alike apart from the red hair thing and they seem very different to me overall.The dresses on the other hand are a different story. It's the exact same dress just different embelishments and a different fabric. I like Amy's take on the dress as it seems somewhat more refined than glitzy. I personally think Isla looks a little over the top in her version.

they both look good, but i don't think the idea of the Oscar's is to repeat a look from the past, Amy could have done so much better!

Oscar Twinkies? I thought it was "twinsies"

I love both of them, but I like Amy's dress better, Isla does look a bit slutty with the shiny fabric and big hair. I don't know who asked, but Amy wasnt in Mean Girls, the blond was Amanda Seyfried.

I love Isla! She's so adorable here with her newly-pregnant glow.

Rachel McAdams was also blond in Mean Girls.

They have to play sisters in something, maybe twins who confuse Vince Vaughn!!

I love them both, their both adorable!!!

I've always thought these two look so similar, so it's funny seeing these pictures where they are dressed like twins!

they both look gorgeous!

Isla is so much hotter! =D

Isla looks way hotter. The green with her brighter red hair mmm reminds me of Jessica Rabbit!

I thought they were the same person for about a year....
I prefer Isla's dress

Love Isla's hair. How do you get that much volume? And her dress is more vibrant.

Oh my God!
They're twins!

But i prefer isla fisher to amy adams.
That amy girl is just getting on my nerves and she's not much of an actress anyway...
pff..

Wow! Just found out tonight that these were 2 different women, LOL! Watched Confessions of a Shopaholic and went to look up Isla as her name sounded odd. It didn't sound like what I'd heard before, but I *knew* (or thought I did anyway) that I'd seen her in Mrs. Pettigrew Lives for a Day and again in Enchanted. Shocked to find out there's more than one of them. Even more shocked to find out Isla is marrying Borat (assuming they can work out their schedules).

i can never get these 2 straight, look like twins to me

OMG! I thought they were the same person!!! I couldn't understand why people kept saying that Amy Adam's acting was great in Wedding Daze, I was thinking "that's Isla Fisher, who the heck is Amy Adams???" and I have seen the movie Enchanted! But all that time I thought Amy was Isla! This is aweful, I can't tell them apart... So, who was the one in "Miss Pettigrew Lives for a Day"??? All this time I thought it was Isla Fisher!
