Costner's 31-year career has long been associated with baseball (Bull Durham, Field of Dreams, For Love of the Game), but his favorite spectator sport is football – association football, that is. "How it started was very innocent: I simply went to an Arsenal game," he says. He first caught the legendary North London-based soccer team in 1990 while filming Robin Hood: Prince of Thieves. Having experienced a match firsthand, Costner has an intimate understanding of the bitter rivalries existing between opposing English soccer teams and their fans. And as such he knows he better avoid Tottenham Hotspur fans in the street at all costs. "They hate my guts, I'm sure of it," he says. For soccer/football newbies, there's no better heartbreak team to latch onto than the dynamic Gunners, who despite many championships are often compared to the perennial underdog Red Sox.
