Kaley Cuoco feared her fans would "hate" 'The Flight Attendant'.
The 35-year-old actress stars in the TV series - which has been nominated for two Golden Globes - but Kaley initially feared it would not be to the taste of her fans.
Kaley - who also serves as an executive producer - told TV Line: "All that went through my mind for the past three-and-a-half years since I optioned this book is, 'Oh my God, am I making a mistake?'
"'Are people going to hate this? Are they going to love it? Oh God, this is so bad, what am I doing? Why am I doing this?'"
The 'Big Bang Theory' star revealed how she witnessed the "struggle" to put the show together as an executive producer and admits it makes the end result "even sweeter".
Kaley said: "Being an executive producer now, you just know way too much, you see all the struggle. As an actor, I get to wake up and walk in, you do your job and then you leave, and you see the end project.
"But learning the road to the end project, it actually makes this even sweeter, because you know how hard to work is, and how much of a huge team effort it takes."
The actress plays Cassandra Bowen, a woman who wakes up hungover in a Dubai hotel room with no recollection of how she got there, and revealed that she hoped to include some comedic elements in the series.
Kaley explained: "I feel that we created a tone that you don't see very often - it wasn't a drama, it wasn't a comedy, it wasn't sad, it wasn't happy.
"It was such a range of stuff, and to be able to make you laugh through some horrors we shot, I feel that's why it was a comedy.
"There were moments that were lighthearted, really crazy comedic moments that we felt were very, very special and that it lent itself to comedy."
