BFI Southbank preview:
Oliver! co-stars Wild and Lester were reunited for Hussein and Alan Parker’s engaging, eccentric child’s-eye-view of Lambeth schooldays. Posh Danny (Lester) and urchin Ornshaw (Wild) are inseparable until Danny falls for classmate Melody, and the pre-teen couple decide to marry. This sweet, uplifting love story has a fab soundtrack by the Bee Gees and Crosby, Stills and Nash.
Here (and above) is the trailer.
