Will Smith [1] appeared on The Tonight Show Starring Jimmy Fallon on Friday to promote his upcoming film Concussion. After talking up the project in an interview, the charismatic actor geared up for a game of Catchphrase along with Jimmy Fallon, The Roots' band leader Tariq Trotter, and special guest Kirsten Dunst [2], who showed up to play on Jimmy's team. Coincidentally, both Will and Kirsten were nominated for Golden Globe Awards this week [3] for their roles in Concussion and Fargo, respectively, and their expert acting chops came in handy for the game. They provided pretty amazing clues for their partners — Will even dropped a Fresh Prince of Bel-Air reference — and even though Kirsten didn't know what a "Saint West" was [4], the game still ended up being a pretty tight race. Watch the highly entertaining video, above, now, and then check out Jimmy's recent sleigh race with Chris Hemsworth [5].
