Tom Hanks has reflected on the scrapped plans for a sequel to his multiple Academy Award-winning outing, Forrest Gump. Following the critical and commercial success of the original, there were many calls for a sequel, with original book author Winston Groom penning his own follow-up, Gump and Co., with original screenwriter Eric Roth also penning a script based on it in 2001. The years since saw the project die in development hell, initially due to the September 11, 2001 attacks, as well as the general lack of interest from Hanks and director Robert Zemeckis in making the Forrest Gump sequel.
