“Boarding” has become an extremely popular term among Hollywood directors. It basically means boarding in a high-paid acclaimed actor for a week or less on the set and paying him less than a full-time job would require.
And while $1 million per day might seem too much if you’re trying to get Bruce Willis into dating you, it seems like Hollywood directors are actually more than willing to pay this sum for a few days if they wish to have Willis on their film set. For example, Willis got paid $25 million for starring in 2007’s “Live Free or Die Hard”, but he requested only $4 million for “The Expendables 3”. Of course, he was willing to take the job for 4 days, but the studio was willing to pay him $3 million, so he didn’t end up in the movie at all. After Willis got boarded in for “GI Joe: Retaliation” and “The Expendables 2” an unnamed movie producer publicly declared that the actor’s salary was $1 million per day.
Meryl Streep, Johnny Depp, Kate Winslet and Dwayne Johnson are also known for being boarded in movies.
