Robert Morse, standing at an exact 5ft 5 (165.1 cm), used his compact frame to infuse his performances with boundless energy and boyish charm, defining his career in theater, film, and television.
- Earning a Tony Award for his star turn as J. Pierrepont Finch in the 1961 Broadway production of How to Succeed in Business Without Really Trying, Morse's height perfectly suited the ambitious everyman climbing corporate ladders.
- He reprised the role in the 1967 film adaptation, showcasing how his stature amplified the character's cheeky, agile persona.
- In Mad Men (2007–2015), Morse's 5ft 5 (165.1 cm) frame brought eccentric gravitas to Bertram Cooper, the short-statured advertising mogul whose larger-than-life quirks stole scenes.
