- ―James Bond and Sylvia Trench.[src]
Sylvia Trench was a fictional patron of the Le Cercle casino at Les Ambassadours in London. A recurring love interest portrayed by British actress Eunice Gayson, the character appeared in EON Productions' first two James Bond films, Dr. No (1962) and From Russia with Love (1963).
At the classy Le Cercle casino in London, James Bond plays Baccarat with a crowd of people. Sylvia sits across the table. It should be noted that Trench can be credited with giving the cinematic Bond his most iconic catchphrase; at the Chemin table, when Bond asks her name, she replies: "Trench, Sylvia Trench" and when she asks Bond his, he replies in the now-familiar style, mimicking (perhaps playfully mocking) Trench's own cadence.
When he receives a message from M and excuses himself, she follows him. He gives her his card and invites her to lunch the next day. After meeting with M, Bond returns to his flat. There, he finds Sylvia putting golf balls into a hat wearing only a button-up shirt of his. Although he must run to the airport, he spends a quick amount of time with her.
Six months later, Trench has a picnic with James Bond beside a river in his car, and notices the scar on his back. Much to her disappointment, Bond is called by Miss Moneypenny for his next mission, to retrieve a coding device from the Russians. Annoyed at the fact as this happened the last time her and Bond were sharing a romantic moment, Trench attempts to woo Bond into staying with her for a little longer before he leaves, but fails as he departs on his mission shortly afterwards.
- Sylvia was the first Bond girl to be introduced in EON's film series.
- Canadian actress Lois Maxwell was originally given the choice of both Sylvia Trench and Miss Moneypenny, and picked the latter (whom she would portray for 14 movies) due to considering Trench's role, which included appearing in an immodest dress, too sexual.
- Eunice Gayson was invited by Terence Young as they worked together in Zarak and he stated that "You always bring me luck in my films".
- Eunice Gayson had "a voice deemed too posh for the character" according to Nikki van der Zyl, so she was brought into dub Sylvia Trench's voice.
- Originally, Trench was to be a recurring character in the films, with the running gag of Bond being called away just as things were becoming interesting. However the idea was scrapped when director Terence Young was replaced with Guy Hamilton for Goldfinger (1964).
- She was the first Bond girl to appear in more than one film, long before Rubelvitch in The Spy Who Loved Me and Octopussy and Madeleine Swann from Spectre and No Time to Die.
- In earlier screenplays the character was named "Sylvia Trenchard".
- Sylvia is the first Bond girl who first becomes acquainted with Bond in a casino. Others from the franchise include Teresa Di Vicenzo from On Her Majesty's Secret Service, Plenty O'Toole from Diamonds are Forever, Lisl von Schlaf from For Your Eyes Only, Solange Dimitrios from Casino Royale and Sévérine from Skyfall. She is also the only one of the above to survive.
