Kurt Russell has that honor, who was paid $15 million for his role as Sergeant Todd in Soldier, which breaks down to $36,855 for each of the 407 words he spoke.
Julia Roberts is the #1 actress in this category, earning $10 million for her role as Tess Ocean in Ocean’s Eleven, which breaks down to $14,599 for each of her 685 spoken words.
It should be noted that while Tom Cruise may be #1 for most amount of money per word overall, he doesn’t hold the top spot for highest-paid actor on a specific project with regard to word count.
