London: Hollywood actor Jake Gyllenhaal read up a lot about Viagra to acquaint himself with the drug for his role in `Love and Other Drugs` and later tested his memory by trying to sell the pill to doctors.

The `Brokeback Mountain` star memorised all the possible side effects of the little blue pill to play a womaniser who embarks on a career as a pharmaceutical
representative, in the upcoming film, a website reported.

"Viagra has a huge booklet on what it is, the side effects and all the chemical components. I would memorise these things. And we would improvise and then I would sell to the doctors," said the 29-year-old actor.

However, the actor refused to comment whether he has tried Viagra in real life.

"There are some things I have to keep for myself," he said.
