Weekes in series two, and starred as Terry Connor in the children's adventure serial The Jensen Code in 1973. He also had guest roles in episodes of popular, established drama series such as Z Cars and A Family at War. While he did not receive the same media attention for his subsequent film performances as he did for Kes, Bradley received solid reviews for his theatre acting. He was cast as Alan Strang in Peter Shaffer's Equus during the mid-1970s. After he succeeded Peter Firth in the role at the Old Vic in London, the production embarked on a 2½-year worldwide tour. In the United States national production, he starred with Brian Bedford, and earned standing ovations and a Los Angeles Drama Critics Circle nomination for Best Actor. Of his performance of the role at the Wilbur Theatre, The Harvard Crimson commented that "Bradley has the most difficult role to play in Equus and he is outstanding." Likewise, his portrayal of the character was praised as being "profoundly sensitive", with reviewer Mark J. Bly of The Heights calling the production "equally as good as its New York counterpart and by all means...not [to] be missed." Bradley also played the role opposite John Fraser in South Africa. He was offered the opportunity to take over the role in the Broadway production, but turned it down due to exhaustion. Additional theatre roles during the 70s included Souplier in Henry de Montherlant's The Fire that Consumes with Nigel Hawthorne, which was staged in 1977 at the Mermaid Theatre. The play, which concerns a priest who is obsessed with a young student, was the recipient of the Society of West End Theatre Award for Play of the Year (now the Olivier Award) and, with Bradley contributing what was referred to as "a beautifully spontaneous performance" as the student opposite Hawthorne's guilt-ridden Abbé de Pradts. Earlier in the decade, Bradley was featured as Hanschen Rilow in the Old Vic's production of Frank Wedekind's controversial tale of sexual discovery, violence, and repression, Spring Awakening, of which Plays and Players stated that "Dai Bradley's Hans is a virtuoso effort, full of awkward and loquacious passion." The production also garnered strong reviews for co-stars Michael Kitchen, Peter Firth, Veronica Quilligan, and Gerard Ryder as the object of Hanschen's forbidden affection, Ernst. Bradley played notable roles in several 1970s films including Malachi's Cove (1973), Absolution (1978), All Quiet on
