As a part of a digital promotional campaign to promote "The Comedy Central Roast of James Franco" on Labor Day, Fallon has created a retro-looking video game where users can smack the Academy Award-nominated actor and former Oscar host in the mug.
Based on a Comedy Central video of Franco getting punched in the face, the game is spoof of the 1980s 8-bit Nintendo video game, "Mike Tyson's Punch-Out!!"
The game can be accessed on Comedy Central's site promoting the show, which will air locally at 9 p.m. Monday.
The direct link to the game is also floating around on social media, like the one from Twitter account Addicting Games below.
An Oscar nominee for the 2010 drama "127 Hours," Franco has also starred in such films as director Sam Raimi's "Spider-Man" trilogy, "Pineapple Express," "Milk" and "Rise of the Planet of the Apes."
