Tom Hanks has provided some tough love for his youngest son Truman ahead of the pair staring in a new film together.
The 66-year-old plays the main protagonist Otto, with Truman playing a younger version of the character.
The film is based on the New York Times bestseller book, which as you'd expect, tell the story of Otto.
The Hanks played character is a grump widower whose only joy comes from judging and criticising his neighbours.
After pushing many neighbours away, Otto meets his match when a young family move in next door.
But that leads to a very unexpected friendship, which will turn Otto's world upside down.
In a new interview, the Forrest Gump actor has spoken about his role playing Otto and how his son Truman fairs playing the younger version.
Speaking on The Graham Norton Show, Hanks said how he told Truman not to rely on their famous last name and instead 'had to hit the marks' when playing Otto.
He said: "Truman plays my character’s younger self, but he’s not the actor in the family - he’s an artist and is going to be a cinematographer.
"We talked about it a lot and it was all his choice, but I said to him, "No matter what your last name is, you are going to have to hit the marks.
"Not everyone is cut out for that, but he did a magnificent job and I thought he was extraordinary."
Later in the interview, Hanks joked that playing the grumpy old man was 'fantastic' as it allowed him 'to release my inner grouch'.
Not only will Hanks be joined by his son for A Man Called Otto, but his wife Rita Wilson is also on the project as a producer.
The trio were seen out in London promoting the new film earlier this week, in what was a rare appearance for son Truman.
Reporters gathered outside of the Corintha Hotel as the Hanks' posed for pictures.
