David Tennant and Krysten Ritter have attended Brazilian fan convention CCXP in São Paulo today to promote their new show Marvel's Jessica Jones. 

After answering questions during a press call, they delighted fans by taking part in a surprise signing session before taking to the stage for their section of the Netflix panel. Unfortunately, due to ongoing technical problems the panel had to be cut short after only 15 minutes in order to accommodate the other Network Original series on show, Sense8.
