American novelist George R R Martin says he does not regret missing Comic-Con 2015 as he was already preoccupied with work.
The 66-year-old writer, whose bestselling series novels "A Song of Ice and Fire" have been adapted by HBO for its dramatic series "Game of Thrones", said it was best to skip comic-con as the cast was already there, reported Entertainment Weekly.
"Staying home was the right decision. It is hardly as if HBO needed me in San Diego to represent... Not with so much of our cast on hand," the author wrote on his blog.

"I have so much work to do, I am way behind on everything... And if truth be told, San Diego has gotten overwhelming in recent years.
"There are always good times catching up with friends, and hanging with the cast, but it's not as if I can walk the floor anymore and look for old comic books, the way I once did... It does make me a little sad, not being there," the author said.
