Scotland has produced some huge Hollywood stars, as well as UK-based actors and actresses -  and a growing number are seeing the benefits of tweeting, as a means to engage and build the fanbase.

We’ve listed  (but not ranked) them by number of followers, knowing that’s only one measure of popularity.

Other factors to take into account in assessing Twitter "influence"  include how many other Tweeters each of our 100 has, in turn, followed to build their audience: the bigger the ratio of followers to following, the more impressive the performance.

And how many Tweets they’ve each put out there: fewer can suggest each word is like gold dust to fans, while more indicates greater interactivity with followers.
