"It's awkward," Falahee, 25, tells ET's Kevin Frazier. "It's 50 or 60 people in the crew watching you, so any time on any project that I've had to do a sex scene it's like, 'Wow, this is the worst.'"
Falahee is one part of a hot young cast that also includes 25-year-old Alfred Enoch (Harry Potter), 28-year-old Matt McGorry (Orange is the New Black), 29-year-old Aja Naomi King (Emily Owens M.D.) and 28-year-old Karla Souza (Instructions Not Included).
The young stars, like the rest of the world, were in awe of their co-star Viola Davis, who immediately set the bar high with the famous way she reads the title for the show's open.
"The first time I heard Viola say it was at the read-through," creator and executive producer Pete Nowalk recalls. "We stopped the read-through and applauded, because it was so much better than we thought it would be."
Executive producer Shonda Rhimes' latest TV sensation follows a group of ambitious law students and their brilliant criminal defense professor Annalise Keating (Davis), who enlists their help with her cases while also inadvertently getting them involved in the murder of her husband.
"Aja does sneak over there sometimes," her co-star McGorry confirms. "We actually have an ankle bracelet for her and any time she goes onto any of Shonda's other lots, it electrocutes her."
In addition to the murder of Annalise's husband on How to Get Away with Murder, another murder mystery is also begging to be solved -- that of Lila Stangard (Megan West), the student who was having an affair with Sam Keating (Tom Verica). Fans will get more of an insight into the whodunnit on tonight's episode airing at 10/9c on ABC.
