The comedian was about to fly from Dulles International Airport in Virginia when an attendant allegedly asked him to move his luggage from the overhead storage cabinet so another passenger could fit her bags in the compartment.
After refusing the request, Colyar became embroiled in a heated discussion with the airline worker and was eventually escorted off the jet.
Colyar claims there was a racial motive behind the request and has now hired top attorney Milton Grimes to pursue the lawsuit, reports TMZ.com.
Grimes was one of the lawyers who successfully represented Rodney King after he was infamously beaten by police in 1991. He eventually won a $3.8 million (£2.4 million) settlement.
The black actor, who voiced a character in Disney's animated The Princess and The Frog, claims a flight attendant on a United Airlines plane in Virginia asked him to move his luggage from the overhead storage bin so a Caucasian passenger could fit her bags in the compartment.
He refused the request and became embroiled in a heated exchange with the stewardess, prompting her to call in security to have him escorted off the plane, which was due to depart Dulles International Airport in Virginia.
Colyar alleges the attendant only called for back-up when he asked about filing a complaint against United Airlines, and he's adamant there was a racial motive behind her actions.
In a post on his blog, he writes, "The flight attendant and her friend got just what they wanted, the n**ger off the plane. I'm sure they feel a great triumph in putting an uppity n**ger in his place.
"At the least I should be suing United Airlines for theft of services, public humiliation and defamation of character."
United Airlines officials are looking into the August (11) incident and a representative tells TMZ.com they are working to resolve the issue with Coylar.
The spokesperson says, "As a global airline with a diverse workforce, United has zero tolerance for any type of discrimination and we take every such matter seriously. We spoke to Mr. Colyar (on) Wednesday (31Aug11) so that we can address his concerns, and committed to get back to him as we learn more from our coworkers and other customers onboard."
Based on a true story The Longshots takes its inspiration from 11 year-old Illinois native Jasmine Plummer’s (Keke Palmer) incredible feat--becoming the only female quarterback ever in the Pop Warner football league. The film’s arc really revolves around the relationship between the young gridiron star and her down-on-his-luck Uncle Curtis (Ice Cube) a former high school football great who can’t seem to do anything right except keep his trouble-prone niece in line. With his own dreams on the field now reemerging in the form of Jasmine the two become an unlikely pair as he gets her to tryout for the all boys local team The Minden Browns. The skeptical coach (Matt Craven) becomes a believer watching her natural talent unfold. When he becomes ill the call goes out to Curtis to come in and help guide the team--now led by the unlikeliest of quarterbacks. In his recent family comedies Are We Done Yet? and Are We There Yet? Ice Cube (who started in gritty movies like Boyz N The Hood) seemed to be turning into the new Tim Allen a safe father figure that would be right at home in a Disney movie. Even though The Longshots is definitely PG it offers him an edgier role and a well-defined character to play for a change. Curtis Plummer is a lazy down and out ex-ballplayer whose passion for life and football have disappeared. Cube at the top of his game gets this guy and gives him three dimensions which makes his later scenes pay off all that much more. Perhaps it was having a real-life person to play that allowed Cube to stretch even in a rather formula vehicle such as this. The other key ingredient that makes Longshots work as well as it does is clearly Keke Palmer who made such a memorable debut in Akeelah and the Bee and confirms her promise as the feisty Jasmine. Together this twosome make The Longshots a pleasure to watch. Second feature by Limp Bizkit frontman Fred Durst is no embarrassment as he clearly is serious about his new directing career and brings out all the action and comedy running through Nick Santora and Doug Atchison’s script. Getting a first-rate performance from Ice Cube and a sterling turn from Palmer proves he knows what he’s doing with actors which is no small task. The game scenes are well-staged and the football stuff seems authentic even though this story of a girl quarterback would not seem that believable if it weren’t true. Still no sports movie cliché is left unturned in The Longshots--right from the title to the end credits--but for some reason it doesn’t seem to matter. There are generous doses of heart and soul on display here making The Longshots a winner for the whole family.
