Charles Stone III (Mr 3000) had been onboard the movie but recently left the film for undisclosed reasons. Rock will star in the comedy and also co-wrote the screenplay.
I Think I Love My Wife is a remake of the French comedy Chloe in the Afternoon and follows a married man (Rock) who is tempted when an old lover re-enters the picture.
Kerry Washington has been tapped to play the old girlfriend. Gina Torres is set to play Rock's wife.
Filming is expected to begin in New York later this month.
