What is the test for damages for a plaintiff who lost out on a chance to become an actor?

52 In a line of cases beginning with Chaplin v. Hicks, [1911] C.A. 786, courts have addressed the difficult task of assessing damages for the loss of an opportunity. In Chaplin v. Hicks, the defendant had published an advertisement in a London daily newspaper announcing a contest for women seeking acting engagements. The advertisement invited applications, from which 300 would be selected. The photographs of the 300 applicants selected would be published in the newspaper, and the readers of the newspaper would select 50. After interviewing the 50, the defendant would select 12 applicants, to whom he would give acting engagements.
