:::::::::::Its called thorough editing.  has already explained this to you but I'll deconstruct these points again. Jackson did not confirm that anybody screen-test, in his interview he did not mention any names. Infact the interview took place before the screen tests were held. The source you posted specifically reads, "We got the news via Collider". Collider reads "Heat Vision reports that actresses screen-testing for the role include Morena Baccarin (V), Jessica Lucas (Cloverfield), Cobie Smulders (How I Met Your Mother), and Mary Elizabeth Winstead (Scott Pilgrim vs. The World)". However Heat Vision only states, "V star Morena Baccarin is on that list", the rest are just "said" to be vying for the part. Grabbing headlines is only half of citing sources, the rest is tracing back to the original report and understanding the language that is actually used.
