Kristen Wiig and Will Ferrell are headed to Lifetime this Saturday in their surprise movie A Deadly Adoption, and the network just released the first full-length trailer. If you had any doubts that Ferrell and Wiig would take their cheesy-dramatic roles seriously, this trailer will put your mind at ease. It also offers the first glimpse of the birth mother in the film played by 90210’s Jessica Lowndes. Watch the drama unfold on Lifetime this Saturday at 8:00pm.
