Los Angeles, California - Succession rules the Emmy nomination list released Wednesday with a whopping 27 nods, including best drama, in an announcement overshadowed by the threat of a Hollywood actors' strike that could derail the industry's entire awards calendar.

For the second year in a row, Succession dominated the acting categories, becoming the first ever show to earn three of the six available slots for best lead actor in a drama.

Echoing their characters in the series, Brian Cox, Jeremy Strong, and Kieran Culkin will now battle each other for the award, while their co-star Sarah Snook is the favorite for best lead actress.

Succession, which has twice won best drama series at the Emmys, was followed in this year's nominations count by two more shows from HBO, which claimed 127 nods overall.
