He won again?

Many people were surprised to hear that the Oscar Leonardo Di Caprio won in 2016 was his first, and are claiming this is a Mandela Effect.

The are sure they remember the ceremony, and even got a strong sense of deja-vu when they saw the 2016 one because they thought his acceptance speech was uncannily similar to the one he gave earlier.

It's been suggested they are confusing this with the BAFTAs, but they are clear they are well aware of that and this is definitely the Oscars.

A Titanic delay

There are reports Di Caprio winning the best actor award for the 1999 Titanic, but records today show that wasn't the case. He'd actually been nominated for 22 years, the first being the 1994 movie "What's eating Gilbert Grape?". He'd been nominated for many awards for years, and won many too including the Best Actor - Drama in 2005 for The Aviator. It's possible that people experiencing this Mandela Effect are just so used to seeing him in a tuxedo and black bow tie at these every year that they are assuming he must have won the big one at some point in his career.
