Continuing their march of worldwide promotional domination, “The Hunger Games: Catching Fire” star Jennifer Lawrence and director Francis Lawrence joined Yahoo CEO Marissa Mayer on November 6 for a live Q&A with their fans as part of the movie’s Global Fan Day.

The questions were — conveniently — culled through Yahoo’s Tumblr Asks series, as Yahoo’s recently acquired microblogging platform also happens to be one where the actress is immensely adored. But the event was key in that it marked the first time Mayer herself hosted a celebrity Q&A on the Yahoo campus. (Yahoo’s partnership with “Hunger Games” studio Lionsgate also extends to the film’s red carpet premiere, of which they will live-stream on November 18.)

Partnerships between Silicon Valley and Hollywood have been prime focuses lately, what with Twitter’s recent pact with Comcast on a “See It” feature that allow viewers to watch TV on the social media site, TV Guide app company i.TV’s purchase of second-screen viewing tool GetGlue and Yahoo’s own Screen mobile video app and partnership with Viacom to license clips of “The Daily Show with Jon Stewart” and “The Colbert Report.”
