Kirk Acevedo (born November 27, 1971) is an American actor. Notable is his portrayal of Miguel Alvarez in the HBO series Oz,
Joe Toye in Band of Brothers(TV miniseries) and his role as FBI Agent Charlie Francis in the science-fiction series Fringe
from 2008–2010. Acevedo's parents were both born in New York City, and lived in Brooklyn
where both their sons, Richard and Kirk Acevedo, were born.
The Acevedos moved to the Bronx, where Kirk and his brother were raised. Since childhood,
Kirk had shown an interest in acting; he would perform before his family in improvised shows.
Acevedo also participated in his high school's drama club. He is of Puerto Rican and Chinese descent. After graduating
from LaGuardia High School of Performing Arts, Acevedo enrolled in the SUNY Purchase School of Acting (Purchase College).
In the 1990s, Acevedo earned his Bachelor of Fine Arts degree and, as some of his classmates had landed parts shortly after auditioning for Oz,
he was also motivated to try out, and subsequently landed the role of the half-crazed gang leader prisoner Miguel Alvarez.

Charles "Charlie" Francis (played by Kirk Acevedo) is an FBI Special Agent, who holds the position of a supervisor.
He is close friends with John Scott and Olivia. Olivia often comes to him with requests for
manpower and other resources. Charlie is later promoted to Second-In-Command of the Fringe division,
making him the immediate subordinate of Broyles. In the season premiere of season 2,
"Momentum Deferred", Charlie is killed by a shapeshift who takes his place. The shapeshifter maintains
his identify for some until it learns the location of Newton, after which Olivia is forced to kill it. Charlie's death weighs heavily on Olivia's guilt.

The Other Universe version of Charlie Francis is alive and an agent of the alternate and more powerful Fringe division.
The alternative Charlie shares many of the same traits as the prime version, though suffers from a parasite infestation in his body,
a fate averted by the prime universe's Charlie in the first season episode "Unleashed".
