In which of these movies did Alain Delon and Jean-Paul Belmondo star?

The movie `Borsalino' (1970), had Alain Delon (1935 - ) and Jean-Paul Belmondo (1933 - 2021) starring as a couple of rivals-turned-partners climbing the ladder of Marseille’s gritty underworld. A predecessor to Marseille crime dramas like Netflix’s Marseille and Matt Damon’s Stillwater, Borsalino sees two perfectly matched actors shine opposite each other. Although Belmondo famously sued Delon over whose name would appear first in the credits they were actually good friends and appeared in several movies together, and are considered to be two colossi of French cinema.

In the 1960s and 1970s Delon was known as one of Europe's most prominent actors and screen sex symbols. He achieved critical acclaim for roles in films such as `Purple Noon' (1960), `Rocco and His Brothers' (1960), `L'Eclisse' (1962), `Le Samouraï' (1967), `La Piscine' (1969), `Le Cercle Rouge' (1970), and `Un flic' (1972).

Belmondo was initially associated with the New Wave of the 1960s and became a major French film star for several decades from the 1960s. His best known credits include `Breathless' (1960), `That Man from Rio' (1964), `Pierrot le Fou' (1965), `Borsalino' (1970), and `The Professional' (1981). He became well known for his unwillingness to appear in English-language films, despite being heavily courted by Hollywood.

When Belmondo died in 2021 the 85 year old Delon said “It wouldn’t be bad if we left together.”
