Men in Black 4: Did the director just tease Will Smith and Tommy Lee Jones will cameo?

Speaking with Entertainment Weekly, he said: “We went into the project knowing the deep affection we and the fans have for Will and Tommy. 

“We’re not replacing them, simply adding to their team.”

The outlet later wrote: “As for cameos by certain Earth-born alumni from past instalments?

“Don’t hold your breath — but okay, maybe go ahead and put it on standby.”

Even if they don’t appear, there’s plenty of room for them to return for Men in Black 5.

After all, Jurassic Park’s Jeff Goldblum did that this year in Jurassic World: Fallen Kingdom.

Men In Black International is released in UK cinemas on June 14, 2019.
