We’ve got two new additions to leading lady casting news today.  Check them out in brief below:

• Viola Davis (The Help) will join Prisoners, a Black List script from Aaron Guzikowski (Contraband) that stars Hugh Jackman (X-Men) and Jake Gyllenhaal (Donnie Darko) to be directed by Denis Villeneuve (Incendies).
• Imogen Poots (28 Weeks Later) will star opposite Zac Efron (17 Again) in Are We Officially Dating?, a romantic comedy from debut writer/director Tom Gormican.

Hit the jump for more on both pictures. 

It appears that Zac Efron is ready to have himself a DTR (“Determine The Relationship”) talk.  Variety reports that Efron has signed on to star in the indie romantic comedy Are We Officially Dating?.  Written by Tom Gormican, the story “follows three friends in Manhattan who make a pact to remain single just as they each start to fall in love.”  Gornican will direct the pic with Treehouse Pictures’ Justin Nappi and Kevin Turen producing.

Efron has been stretching his acting chops lately as he stars in Lee Daniels’ upcoming polarizing drama The Paperboy alongside Nicole Kidman, he’s set to star in Adam Shankman’s adaptation of the novel This Is Where I Leave You with Jason Bateman, and he’ll appear opposite Seth Rogen in the Nicholas Stoller comedy Townies.

Warner Bros. has hired scribe Tom Gormican to adapt the etiquette writings of the late Emily Post. According to THR, the untitled project will be in the vein of Audrey Hepburn and Rex Harrison’s 1964 classic My Fair Lady and will tell the story of “a prissy Emily Post manners coach who attempts to turn a guy’s guy into a refined gentleman.” Gormican’s previous output includes the Black-List alum Are We Officially Dating?. He has also sold a romantic-comedy pitch entitled Save the Date which Neal Mortiz will produce.
