2. David Lean and Alec Guinness (Director/Actor, 6 collaborations)
David Lean and Alec Guinness, the meeting of two giants of British, and any, cinema. What really needs to be said? Great on their own, never better working together. From Great Expectations to Passage to India, Guinness appeared six times in a Lean film, in both leading and supporting roles. Portraying everything from Englishman to Arab, to Russian and Indian (impressive, no?). Of course, his most prominent role was as P.O.W Colonel Nicholson in The Bridge on the River Kwai, which won the duo near-universal acclaim, leading to Oscars for both its star and director. They would have been great in their own rights, but their better success as a team more than deserves a spot here. However, they are bested by perhaps the greatest duo in filmmaking history...
