Colin Callender, HBO Films President, announced on Tuesday that he intends to leave the big company after 20 years of making HBO one of the most important film networks. Callender added that he wants to start on with a new entertainment company. At HBO, he was the executive responsible for the channel’s ambitions, sophisticated and the most expensive movies.

Callender said during a conference call that this was “solely” his decision “to leave and return to” his “entrepreneurial roots.” Before he announced he would leave the company, he didn’t leave HBO on its own. He left some continuous plans to be made before a new president manages to truly take his place. Callender included into the channel’s program the miniseries “John Adams,” which won 13 Emmy Awards.

Also the drama about the 2000 presidential vote in Florida, “Recount,” and “Generation Kill” remained in HBO’s program to still keep its viewers. When Chris Albrecht, former boss at HBO, left the company last year, Callender already lost some of his influence as the new management structure diminished his autonomy.
 
HBO is owned by Time Warner Inc. and the big company has to deal with many challenges like competition on its own and from the beginning again. After series like “The Sopranos” and “Six Feet Under” won a lot of prizes, HBO has now to find another hit series. And the competition grows even bigger as shows like “Weeds” or “Dexter” from Showtime announce a new first place.

This year, Time Warner Inc. decided to close its Picture house movie label, which released movies like “American Splendor” or “Pan’s Labyrinth” and this was a minus point for HBO. Now, two of Callender’s subordinates will take his duties on. Kary Antholis and Len Amanto will be the next ones to save HBO network.
