Chok's main theatre roles have included parts in the award-winning Lucy Kirkwood play Chimerica, as part of the original cast at the Almeida and Harold Pinter theatres and in The World of Extreme Happiness, in which she co-starred with Katie Leung. Chok played the part of Ming Ming, a female migrant worker, in a production about the world of migrant workers in rapidly emerging modern China. Vera Chok also appeared in the TV miniseries version of Chimerica on Channel 4 in 2019, alongside Katie Leung. In 2015, Chok appeared in Nicholas Hytner's final production as artistic director for the National Theatre, Tom Stoppard's The Hard Problem. The play was Stoppard's first for the theatre since 2006 and a special screening was broadcast live to cinemas. She subsequently had roles in the Kenneth Branagh Theatre Company production of The Winter's Tale at the Garrick Theatre in late 2015 and an associated work, Terence Rattigan's Harlequinade, also at the Garrick, which humorously depicts a postwar CEMA-sponsored theatrical troop at a provincial theatre in Brackley making a hash of Romeo and Juliet and "the intrigues and dalliances of the company members". Chok was nominated in the 2015 BBC Audio Drama Awards for her performance in the BBC Radio 3 production of British Chinese novelist Xiaolu Guo's first play, Dostoevsky And The Chickens, in which she co-starred. In Liao Yimei's comedy dramaRhinoceros in Love, also for Radio 3, she plays the beautiful Mingming, the object of a zookeeper's longing, in a performance described by the Sunday Times as 'bewitching'. She appeared in Jingo and played the lead role of Lila in the stage adaptation of Philip Pullman's The Firework-Maker's Daughter - described by The Stage as a 'poignant performance'. In addition, Chok has appeared in a number of independent and main release films, in the long-running ITV series Coronation Street and in TV dramas for the BBC, Netflix and Sky. Whatsonstage.com named her one of "15 theatre faces to look out for in 2015". Asked by the magazine to give her advice on International Women's Day, Chok said "Play the long game: stay open, generous, and keep developing your craft." In 2016, she contributed a chapter to the widely publicised anthology of the personal accounts of members of immigrant and ethnic minorities in the UK, 'The Good Immigrant'. Writing about her experiences as a Malaysian immigrant in Britain in the Guardian during Black History Month, Chok commented on the invisibility of 'East Asian' groups in Britain: "In the UK media, we don’t see south Asians portrayed in a way that reflects their position as the largest racial minority group in the UK. East Asians, the third-largest and fastest-growing racial group at 1.2 million, people bear the damning “model minority” label which isolates them from other people of colour, and condemns them to an invisibility where violence against them is ignored." Writing in British Chinese journal Neehao in 2017, she urged British Chinese and East Asian actors not to take on parts that reinforce anti-China sentiment at a time when "...asians in America, in LIBERAL states, are being beaten up because of anti-China rhetoric from D T."
Producing
In 2010, Chok founded saltpeter, an independent theatre company. She produced and starred in their opera production Tonseisha - The Man Who Abandoned the World, which is adapted from the play by Erik Patterson. In the work, which features opera, dance and theatre, Chok played Yukiko, a Japanese woman haunted by the losses of her father and Beat writer Richard Brautigan. In 2011, she founded the Brautigan Book Club, which stimulates creative explorations based on Brautigan's work.
