In 1996, Leo and fellow up and coming stars Tobey Maguire and Kevin Connolly acted in an improvised film project, “Don’s Plum.” No contacts. No script. What could go wrong? Now, 23 years later, two of the filmmakers — Dale Wheatley and Tawd Beckman — open up about the best and worst times of their lives. This is when life was good. This is when the friendships were good,” Wheatley told The Post. Little did he know this “film with our friends” would eventually be blocked by its stars. Find out the true, untold story in the premiere episode of “The Curse of Don’s Plum” by the New York Post.
