Bruce Willis is set to begin filming Die Hard 5 next year, if you trust Puerto Rico's second-largest newspaper "Primera Hora." I personally only trust their first largest. Latino Review (ooooh how convenient) reports:
According to the newspaper, (which is in Spanish) it quotes Gustavo Rivera Aparicio, who's credited as general manager of 20th Century Fox offices in PR, as confirming that "Die Hard 5" will film in Puerto Rico in 2011. The announcement was made jointly with the Puerto Rico Film Commission.

Aparicio says the decision was spurred by the succesful [sic] filming of Fast Five in early 2010, and Pirates of the Caribbean: On Stranger Tides a few months ago.

These is big news, you guys. I just learned that 20th Century Fox has general manager in Puerto Rico. That guy must party so hard in between film shoots. Anyway, I hope this news is true. Live Free or Die Hard wasn't fantastic, but it was definitely a helluva lot of fun. I say keep on making Die Hards until Willis has to remove his breathing apparatus to sputter out, "Yippee ki yay, motherfucker."
