Dewey & LeBoeuf and Paul, Hastings, Janofsky & Walker landed leading roles on Walt Disney’s $4 billion cash and stock acquisition of Marvel Entertainment, a deal that gives Disney the rights to more than 5,000 Marvel characters, including Iron Man and the Incredible Hulk.

Dewey’s representation of Disney, a longtime client of M&A Chair Morton Pierce, reaffirms the firm’s role as the Mouse’s go-to outside counsel. Disney used Skadden, Arps, Slate, Meagher & Flom as lead M&A counsel for its last megadeal, the $7.4 billion acquisition of Pixar Animation Studios in 2006, according to The National Law Journal. (Dewey played a secondary role in that deal because the firm was working on a different Disney deal at the same time, according to the NLJ story.)
