<Li> Clark Gregg as Phil Coulson: A rookie agent of S.H.I.E.L.D. who works closely with Fury . Gregg stated that Coulson would be younger in the film and "a bit of a new guy in S.H.I.E.L.D....It's the earliest we will have seen him (in the MCU), so when he says,' Mr. Stark, this isn't my first rodeo' in Iron Man, this is maybe the rodeo he's talking about ." He felt "there was something really special about going back to the early days when (Coulson) was just kind of coming up the ranks" and had to work to portray Coulson "a little less crusty and jaded" as he is in the present of the MCU . Like Jackson, Gregg was digitally de-aged by 25 years, the first time Marvel has done this for an entire film . </Li> <Li> Jude Law as Mar - Vell / Walter Lawson: Danvers' mentor and commander in Starforce, who trains her to use her new powers . Law said that his character is "driven by a belief in the divine leadership of the Kree people . So he's almost a devout warrior--unquestioning, conservative, but inspirational ." Law also stated that his character has a special relationship with Danvers, whom he views as a mentee, which becomes a source of tension in the film with the other members of Starforce . Robert Downey Jr., who portrays Tony Stark in other MCU films and who co-starred with Law in Sherlock Holmes and its sequel, counseled him on working with Marvel, before Law took the part . </Li> <P> Additionally, Robert Kazinsky, Annette Bening, Vik Sahay, Colin Ford, Chuku Modu, and Kenneth Mitchell have been cast in undisclosed roles . </P> <P> By May 2013, a script for Ms. Marvel, the moniker Carol Danvers used in the comics before she took the mantle Captain Marvel, had been written for Marvel Studios through the studio's writing program . Producer Louis D'Esposito stated later that year that the studio was interested in a female - driven superhero film, saying that they have plenty of "strong female characters" from which to choose and suggested Captain Marvel, Black Widow, Pepper Potts, or Peggy Carter as possible candidates . Kevin Feige, President of Production at Marvel Studios, said that if Marvel was to make a female - led film, he would prefer it to be a new character to the Marvel Cinematic Universe like Captain Marvel, who could receive an origin story . In August 2014, Feige stated that Black Panther and Captain Marvel were "both characters that we like, that development work has been done on and is continuing to be done on" and that the studio is often asked about it by the public, "more than Iron Man 4, more than Avengers 3...I think that's something that we have to pay attention to ." </P>
