I chose the name of my pet based on Hollywood movie stars.
I called my pet after the name of Hollywood movie stars.

Thank you in advance.

Really? More than one movie star?

My guess is that you mean one of the following:
I named my pet after a Hollywood show. I call him "Chaparral."
I named my pet after a Hollywood movie star. I call him "Cameron." (Cameron Mitchell was an actor.)
I named my pet after a movie character. I call him "Buck.." (Buck Cannon was a character in the show.)

("I chose the name of my pet based on . . . " is quite correct grammatically, but "I named my pet after . . . " is more idiomatic.)

Yes, I named my pet after a Hollywood movie star. I called him Steve after Steve Mcqueen.Emotion: smile
Sorry Clive, Chaparral was a weekly movie, not a program. Can I say, a weekly serial? By the way what is the differences between series and serial?
Hi,

High Chaparral was a TV series, not a movie.
http://en.wikipedia.org/wiki/The_High_Chaparral

Almost anything that runs on TV, except a movie, is casually called 'a program'.

'A series' is several episodes, each consisting of a self-contained story about the same characters and with the same setting..

'A serial' usually refers of a single story that continues through all the episodes.
