Fans go wild as they spot Scarlett Johansson playing the sister in Home Alone as they say: ‘How the heck did I not know this?’

Fans went into overdrive when they learned that a young Scarlett Johansson was starring in the holiday cult franchise Home Alone 3.

The 39-year-old Black Widow actress played Alex Pruitt’s (Alex D. Lintz) sister Molly when she was 11 years old.

In the third installment of the holiday film series, young Alex battles international terrorists after a microchip hidden in a toy car is mistakenly placed in his care.

Alex, unwell and at home with chicken pox, notices intruders ransacking the house of his hapless neighbor, Mrs. Hess, in an attempt to find her car and microchip.

After the thieves realize Alex has been spying on them, they decide to target the Pruitt home, and the Chicago boy is forced to defend the family home.

But fans are also shocked that they didn’t recognize Scarlett, who played the title character’s indifferent older sister.

Taking to X, formerly known as Twitter, one fan wrote: “How the hell didn’t I know Scar Joe was in Home Alone 3??????”

“Damn… Scar Joe was in Home Alone?… Wow,” another added: “Joe Scar in Home Alone 3 and I’m just blown.”

“How could I even tell that Scar Jo was the sister in Home Alone???”

“Damn, I never thought Scar Joe was in Home Alone 3,” one joked.

Others were a little more shocked by the revelation, adding: “Scar Joe is in Home Alone 3 and I’m just blown.”

“Damn, I didn’t know Scar Jo was the sister in Home Alone 3.”

However, not only fans did not recognize the Lost in Translation actress; even her own daughter did not notice her in Home Alone 3.

During a speech at Late Night with Seth Meyers In 2021, the actress shared that her daughter was not shown the film on purpose; naturally, it was released.

She said: “Of course, naturally, we did Home Alone.” And I happened to be in the third Home Alone movie, so I didn’t tell her anything because I thought she’d make a big deal about it.”

But six-year-old Rosie didn’t “immediately” realize that Molly Pruitt was actually her mother, the actress said.

“I actually had to (say), ‘Look who it is?’ She (Rosie) was like, “Whatever. It’s you?” I was like, “It’s me, your mom.” And she was like, “Oh, okay. Whatever”.’

But fans weren't the only ones who didn't immediately recognize the young actress - even her six-year-old daughter Rosie took a while to notice her mom.
