Will Smith's latest summer blockbuster, Suicide Squad, is set to open this weekend, and it's already getting glowing reviews from his family.
At the New York red carpet premiere on Monday, the 47-year-old Oscar-nominated actor revealed to ET that his sons Trey, 23, and Jaden, 18, -- who were on hand to support their dad -- were already seeing the movie for the second time.
"They saw it three days ago, and they're coming to see it again. They told me I don't ever have to work again," Smith joked to ET. "They said this is it. I'll never make anything better than this. Deadshot is the best character I will ever play, and I need to stop making movies. That's the family consensus."
Smith's character, Deadshot, is the world's deadliest and most accurate marksman. In the movie, he is joined by Joker (Jared Leto), Harley Quinn (Margot Robbie), and other supervillains who have been recruited by the government to execute dangerous black ops missions in exchange for clemency.
The role of Deadshot required a drastically different look for Smith -- he shaved his head and grew a beard for the movie -- but his wife Jada wasn't mad at the change.
"She appreciated it," Smith teased. "I wanted to bring the outfit home. It's just that it takes 40 minutes to get off, so by that time you kind of lose the mood."
While all the actors unleashed their dark sides on camera, off-camera they kept the mood light.
"You get to those points after you've worked for like 8 or 9 hours and the set starts to be dead, and I mean I'll bust out some show tunes, or something like that," Smith said. "I would start with 'Somewhere Over the Rainbow,' you know what I mean? A little Dorothy never hurt nobody."
In addition to the sing-a-long sessions, Smith also kept up morale with the invention of Willyville -- a section of the set for recreational activities like a basketball court and ping-pong table where the cast and crew could kick back.
"When you make a movie like this, especially this size of a movie, with that kind of scope you're spending 16 to18 hours on the set sometimes, so I like to create a place where everybody can kind of chill, and have a good time," he said.
Suicide Squad opens in theaters on Friday.
