A lot of celebrities look alike. For example, the trifecta of is almost spooky. But to hear fans say that they've previously confused Sandra Bullock and Julia Roberts? That sounds like a bad joke!

And yet, some fans swear that they couldn't tell the two lead actresses apart, and it's not just because they're both sort of brunette and have somewhat similar features.

Fans Say They Had Trouble Identifying Julia Vs. Sandra

Before any more mature film enthusiasts start grumbling about youngins these days, did admit they weren't very familiar with either Sandra or Julia's work because of the generation they grew up in.

For anyone who watches either iconic actress infrequently, honest mistakes can happen. Right?

But on the face of it, it doesn't seem like Julia Roberts and Sandra Bullock really look alike. At least, not as similar as , or the strikingly similarly redheaded Jessica Chastain and Bryce Dallas Howard.

Though they may not look similar enough to be confused for each other on the street, fans are essentially saying that Julia Roberts and Sandra Bullock are sort of interchangeable in their roles.

Plus, so many commenters noted that they had Julia Roberts confused with various other actresses (like Kyra Sedgwick in 'The Closer'), which led the OP to joke, "What I'm hearing is Julia Roberts isn't real."

It seems like for every person who's incredulous that a moviegoer could confuse Julia and Sandra, there's another who's willing to confess they had the same confusion over the years. Finally, closure for those people who had no clue what was happening when Julia/Sandra was literally .
