The 38-year-old actor plays Martin Luther King in the film about the 1965 campaign in Selma, Alabama, for equal voting rights for African-Americans.
The film, out in the UK next week, has been lauded by critics but received no Bafta nominations, reported BBC online.
The film received two Oscar nominations - for best picture and best original song.
"When it's the best reviewed film of the year, and it's a film of this significance, and you have British company Pathe producing it, and you have four Brits as the main characters of the film, you expect to be nominated for Baftas," Oyelowo said.
