The move comes almost three months after the arrival of Elizabeth Kesses from the communications agency Ingram, as Twentieth Century Fox’s theatrical marketing director.
Kesses will oversee the review which has been called to beef up the film and home entertainment company’s planning and strategy expertise.
Twentieth Century Fox uses more than 12 roster agencies, but declined to disclose names.
Kesses said the review is already underway but she does not expect to make any wholesale changes to the roster, and would not rule out working with agencies she has worked with in the past.
She said: "I just want to refresh the roster and see what's out there. We use lots of creative agencies, I'm just taking stock of my options."
At the end of last year, Fox strengthened its relationship with the communications agency Ingram, which provides it with global strategy advice. Soon after this, Kesses, a former managing partner at Ingram, joined Twentieth Century Fox.
In January, Twentieth Century Fox awarded the European, Asian and Latin American portions of its media account to Vizeum. The consolidated business is estimated to worth £150m in terms of billings.
The US and Australian media accounts were picked up by Zenith Media Services.
This summer's movie releases from Twentieth Century Fox will include 'Die Hard 4.0', 'The Simpsons Movie' and 'Fantastic Four: Rise of the Silver Surfer'.
