'Fast X' star explains why Han's hair is longer now even though there's no time jump between his last appearance and the new movie

• Warning: There are mild spoilers ahead for "Fast X."
• Han's hair goes from short to long during the continuation of a mid-credits scene from "Fast 9."

Sung Kang knows you may scrutinize his hair during one scene in "Fast X."

At the end of 2021's "Fast 9," Kang's character, Han, paid a visit to Deckard Shaw (Jason Statham) with extremely short hair.

The "Furious 7" villain seemingly killed Han several movies back and a meeting between the pair was years in the making.

However, when the highly-anticipated confrontation plays out in "Fast X," audiences see a reshot scene with Han sporting much longer hair.

As a result, the two scenes don't quite match up.

"The reason I wanted Han's hair to be short was that he's in hiding," Sung Kang told Insider of Han's different look in "F9." "So if he's walking around looking like Han it doesn't really make any sense to the character. You cut his hair, he kind of blends in."

Believed dead for years, Dominic Toretto (Vin Diesel) and his crew didn't learn their friend faked his death until the 2021 film.

When returning for "Fast X," Kang recommended that Han's hair revert to a recognizable style.

"I realized that there are a few things that people need from Han. They want snacks, they want cool cars, and they want his hair," Kang said. "The hair is almost like a superpower he has... It's synonymous to what defines Han."

Unfortunately, Kang said he didn't realize the "Fast 9" mid-credits scene with Han's short hair would take place years later in the "Fast" timeline.

When watching the 2021 movie, it's easy to presume the end tag takes place shortly after the events of "Fast 9."

That's not the case.

Though there's about a four-year time jump between the events of "Fast 9" and its sequel, the "F9" mid-credits scene takes place during the events of "Fast X."

When Insider asked Kang whether or not he was asked to cut his hair for continuity in "Fast X," Kang told Insider, "Yes."

But that wasn't going to happen.

Han's hair became a major topic of conversation during the making of the sequel to figure out a fix, resulting in the behind-the-ear tuck we see on-screen.

"Because everybody is OCD about their work and they're into details, details are what matters, there were a lot of notes and discussion about, 'Hey Han's hair in the tag is short. How are we gonna do it?' And we did these tests where you get really close with the tucked-in hair. It could kind of match," Kang said.

So before you go and poke fun at Han's "Fast X" hair for not matching his "F9" hair, know there was a lot of thought that went into trying to create an illusion for the scenes to look somewhat similar.
