Believe It Or Not! written by Scott Alexander and Larry Karaszewski.

05/06/05 draft, cover + page 3 (intro of Robert Ripley).

Alexander & Karaszewski (People vs. Larry Flynt, Ed Wood, Man on the Moon) wrote for Paramount with Tim Burton attached to direct, and Jim Carrey to star. Chris Columbus replaced Burton in 2009, and worked with John Collee on a new script. Most recently in 2011, Eric Roth was hired to rewrite. Jim Carrey was still attached.

The Apartment by Billy Wilder and I.A.L. Diamond.
Mr. Wilder and Mr. Diamond won the 1960 Oscar for Best Original Screenplay. 
A personal note: Billy Wilder was one of the first Hollywood legends I ever saw in person, in 1994, at The Grill in Beverly Hills. He was eating lunch with Warren Beatty.
