Katheryn Winnick spilled the beans on the extended Season 4 of Vikings to IGN during San Diego Comic Con this year.
Of course, with more episodes, that also gives the opportunity for new cast members. Katheryn Winnick (who plays Vikings fan favorite, Lagertha) confirmed at San Diego Comic Con that there would be 'double the amount' of Vikings episodes next year. Fans of History Channel's Vikings can now rejoice in the fact that Season 4 will have more episodes than previous seasons.
