Star-studded describes an event, a film, a show, or a list of names that is packed with famous performers — not one star, but many, scattered all through it. A star-studded cast, a star-studded charity concert, a star-studded opening night.

Star-studdedstar-studded describes形容 an event, a film, a show, or a list of names一個活動、電影、節目，或名單 that is packed with famous performers裡面滿滿都是知名藝人 — not one star不只是一個明星, but many, scattered all through it而是很多個，散布在整個裡面. A star-studded cast, a star-studded charity concert, a star-studded opening night像「star-studded cast」、「star-studded charity concert」、「star-studded opening night」（眾星雲集的卡司、明星雲集的慈善演唱會、星光熠熠的開幕之夜）.

The feeling of the word is bright and a bit breathless. It belongs to entertainment news, posters, and press releases; it is how publicity talks. A serious film review would more likely say 'an unusually strong cast'.

The feeling of the word這個字給人的感覺 is bright and a bit breathless是明亮、還帶點興奮喘息的. It它 belongs to entertainment news, posters, and press releases屬於娛樂新聞、海報，還有新聞稿; it is how publicity talks是宣傳圈的講法. A serious film review一篇正經的影評 would more likely say比較可能會說 'an unusually strong cast'「an unusually strong cast」（陣容格外堅強）.

If you use star-studded in an academic essay it will sound out of place, and if you use it about your friend's birthday party it will sound like a joke — which is a perfectly good way to use it.

If you use star-studded如果你把star-studded用 in an academic essay在學術論文裡 it will sound out of place會顯得格格不入, and而 if you use it about your friend's birthday party如果你用它來說朋友的生日派對 it will sound like a joke會聽起來像在開玩笑 — which is a perfectly good way to use it而這其實是很好的用法.

One more thing: the word says how many famous people were there, not how good the thing was. A star-studded film can still be terrible, and critics enjoy pointing that out.

One more thing還有一點: the word這個字 says how many famous people were there說的是有多少名人到場, not how good the thing was不是說這件事本身有多好. A star-studded film一部星光熠熠的電影 can still be terrible還是有可能爛透了, and critics enjoy pointing that out評論家還很愛把這一點指出來.
