Ehrenreich was talking about his portrayal of Han Solo, the young, intergalactic pilot and smuggler he plays in "Solo: A Star Wars Story."
Ford played an older version of the iconic character in four "Star Wars" blockbusters.
"The only thing better than one Han Solo is two. Harrison Ford dropped by @CameronMathison's interview and surprised #SoloAStarWarsStory star Alden Ehrenreich!" the Entertainment Tonight Twitter account teased Saturday.
The brief video shows Ehrenreich talking to a reporter when Ford walks in behind him with Solo director Ron Howard.
"Oh, my God!" Ehrenreich exclaimed.
"Get out of my chair. Get out of my life," Ford growled before shaking hands with and hugging the younger actor as Howard clapped and everyone in the room laughed.
Ford and Howard have been friends for decades after co-starring in the 1973 movie "American Grafitti," which was helmed by "Star Wars" creator George Lucas.
