Sarah Silverman in talks to join Seth MacFarlane’s new comedy western film

The film's cast already includes Liam Neeson, Charlize Theron and Amanda Seyfried

Comedian Sarah Silverman looks set to join the ever-swelling cast of A Million Ways To Die In The West, Seth MacFarlane‘s follow-up to Ted.

According to The Hollywood Reporter, Silverman is “in negotiations” to play a prostitute with a confusing moral code: though she performs sexual favours for money, she refuses to gratify her fiancé because she doesn’t believe in sex before marriage.

The comedy western film already boasts a strong ensemble cast including MacFarlane, Liam Neeson, Charlize Theron, Amanda Seyfried and Giovanni Ribisi, who has been cast as the prostitute’s sexually frustrated fiancé.

MacFarlane will star as a cowardly chicken farmer who gets dumped by his girlfriend, played by Seyfried, and looks to Theron’s character, a mysterious new woman in town, to teach him courage. Neeson will appear as the newcomer’s outlaw husband, who turns up unexpectedly and tests the farmer’s courage.

MacFarlane is also directing the film from a script he penned with his Ted co-writers Alec Sulkin and Wellesley Wild. Shooting is due to begin this May.

Meanwhile, MacFarlane has recently revealed that “everybody involved” wants to make Ted 2, though nothing is officially in the works yet. He has also expressed an interest in bringing Family Guy to the big screen, saying it’s “just a matter of when”.
