謝立文喺赤柱聖士提反書院讀中學。《麥兜》入邊嘅「春田花花幼稚園」，部份係佢母校嘅回憶。例如黃秋生配音嘅校長同黎根，就係按照佢讀書嗰陣個校長葉敬平個樣刻畫，所以啲舊生睇到無不拍案叫絕。《麥兜》動畫版入邊好多歌都係由校友何崇志博士填詞及編曲。
Tse is a secondary school student at St. Stephen's College in Stanley. The "Springfield Flower Flower Kindergarten" in "McDull" is partly a memory of his alma mater. For example, the principal and Li Gen dubbed by Huang Qiusheng are portrayed according to the appearance of the principal Ye Jingping when he was studying, so some old students are all amazed when they see it. Many of the songs in the animated version of "McDull" were written and arranged by alumnus Dr. Ho Chongzhi.
