Miller, known more for his visual flair than for the brash antics that Reynolds and his writers embraced and that fans loved, wanted a more stylish take, one that would compete with mega-budget superhero movies, insiders said. But it would have cost three times as much as the original $58 million film, the first individual said.

"There were two totally different movies on the table, and one of them just wasn't 'Deadpool," said the first insider, who is familiar with both concepts.

Reynolds, Reese and Wernick's vision won.

Sounds like Miller wanted to go big budget and Reynolds wanted to stick with what they did for the first one.
